Naval  Consulting  Board  and  Related  Wartime  Research  Papers 

These  papers  deal  with  two  aspects  of  Edison's  work  during i  World  War  I: 
his  role  as  chairman  (later  president)  of  the  Naval  Consulting  Board  (NCB), 
beginning  in  1 91 5;  and  his  personal  experimental  workforce  U.S.  Navy  and  U.S. 
Army,  which  began  early  in  1917  and  took  up  much  of  his  time  until  the  end  of  the 
war.  Although  these  two  functions  were  not  formally  retested,  they  often 
overlapped,  and  documents  concerning  both  the  NCB  and  Edison  s  personal 
research  appear  in  this  record  group. 

The  NCB  was  created  in  July  1915  as  the  result  of  discussions  between 
Edison  and  Secretary  of  the  Navy  Josephus  Daniels,  with  the  advice  of  Miller 
Reese  Hutchison,  Edison’s  chief  engineer  and  personal  representa  ive.  The 
Board's  membership,  confirmed  at  its  first  meeting  in  October  1 91 5,  included  two 
representatives  from  each  of  the  eleven  professional  engineering  societies  as 
well  as  Edison  and  Hutchison.  The  NCB  was  organized  into  technical  comm  ttees 
on  various  subjects,  with  a  view  to  industrial  preparedness  should  the  United 
States  be  drawn  into  the  European  war. 

One  of  the  Board’s  initial  responsibilities  was  to  evaluate  suggestions  for 
inventions  from  the  public,  which  quickly  became  a  huge  a"d.es^rlt|lftJiyn  ^'t'e^ 
task  The  NCB  operated  in  a  purely  advisory  capacity  until  it  was  authorized  by 
Congress  in  August  1916,  after  which  it  began  to  plan  for  its  own  research 
laboratory.  Although  frequently  discussed,  the  laboratory  was  not  bulk  unt well 
after  the  war  due  to  fundamental  disagreements  between  Edison  and  the  younger 
generation  of  researchers  about  how  technological  research  shou  d  be 
conducted.  Edison  insisted  that  a  large  industrial  workshop  near  New  York  City 
was  required,  while  others  believed  that  a  facility  for  research  in  basic  science, 
neargovernment  and  military  headquarters  in  Washington,  would  be  moreuseful. 
With  the  U.S.  entry  into  the  war  in  April  1917,  the  Board  s  attention  shifted  to  the 
more  immediate  problem  of  defense  against  German  submarines. 

Edison's  role  on  the  NCB  had  always  been  largely  ceremonial  with  the 
administrative  work  carried  out  by  first  vice  chairman  William  L-  Saunders  and 
secretary  Thomas  Robins.  Beginning  in  1917,  however,  Ed'son  devoted  ^most 
all  of  his  time  to  a  variety  of  research  projects  that  he  conducted  both i  pers  y 

and  with  the  assistance  of  experimenters  working  at  various  locations  in  New 
Jersey  on  Long  Island,  and  later  at  Key  West.  His  results  and  expenses  were 
reported  to  Secretary  Daniels,  but  to  Edison's  disappointment  the  Navy  dechned 
to  take  up  any  of  his  inventions  and  by  October  1919  the  government  had 
stopped  funding  his  military  research. 


The  folders  contain  documents  on  three  distinct  subjects,  in  varying 
proportions  according  to  the  year:  unsolicited  letters  from  the  general  public; 
correspondence  relating  to  the  business  of  the  NCB;  and  communications  among 
Edison,  his  experimental  staff,  Naval  officers,  government  officials,  and  private 
companies,  relating  to  his  personal  research  projects.  The  folders  for  1919-1920 
also  contain  correspondence  with  Capt.  Lloyd  N.  Scott  and  others  pertaining  to 
Scott's  official  history,  Naval  Consulting  Board  of  the  United  States  (Washington, 
D.C.:  Government  Printing  Office,  1920). 

Approximately  25  percent  of  the  documents  have  been  selected,  including 
ail  items  pertaining  directly  to  Edison.  Routine  documents  sent  to  Edison  as  an 
official  of  the  NCB  have  not  been  selected.  Also  unselected  are  the  vast  majority 
of  war  invention  ideas  submitted  by  the  public,  few  of  which  received  a  substantive 
reply.  More  specific  selection  statements  can  be  found  in  the  editorial  descriptions 
preceding  each  folder. 

Material  pertaining  to  the  experiments  discussed  in  these  documents  can 
also  be  found  in  the  Notebook  Series:  (1)  Notebooks  by  Edison,  N-17-01-20 
through  N-1 8-07-1 8.2  and  N-18-1 1-03;  (2)  Notebooks  by  Edison  and  Other 
Experimenters— Navy  and  Wartime  Research  Experiments;  and  (3)  Notebooks  by 
Experimenters  Other  Than  Edison— Navy  and  Wartime  Research  Experiments. 
Correspondence  and  other  documents  similar  to  those  in  the  Naval  Consulting 
Board  Papers  can  be  found  in  the  Edison  General  File  for  1915-1919  in  "Advice/ 
"Naval  Consulting  Board,"  "Naval  Experiments,”  "Radio,"  "Roosevelt,  Franklin  D," 
"World  War  I— Experimental  Work,"  and  other  folders  for  these  years.  Additional 
correspondence  between  Edison  and  Daniels  can  be  found  in  the  Josephus 
Daniels  Papers,  Charles  Hummel  Collection,  Thomas  A.  Edison  Papers  Digital 
Edition,  XI 28C.  A  scrapbook  of  newspaper  clippings  (Cat.  44,452)  relating  to  the 
NCB  and  the  war  generally  can  be  found  in  the  Scrapbook  Series. 


The  documents  appear  on  the  microfilm  in  the  following  order:

A  Note  on  Arrangement 


The  archival  record  group  at  the  Edison  National  Historic  Site  contains  two 
series:  a  main  run  of  general  correspondence  organized  chronologically  from  1915 
through  1930  (boxes  1-20);  and  a  smaller  collection  of  subject  folders  (boxes  21- 
24)  containing  additional  correspondence  along  with  test  reports,  experimental 
notes,  printed  material,  and  other  documents.  Although  the  names  of  the  folders 
in  the  archival  record  group  reflect  the  original  subject  headings  created  by  Edison 
and  his  secretaries,  these  names  are  occasionally  misleading  and  many  of  the 
items  within  the  folders  do  not  fall  under  the  stated  subject.  In  addition,  documents 
about  a  particular  subject  are  sometimes  scattered  among  several  subject  folders 
and  related  material  can  often  be  found  as  well  in  the  general  correspondence 
folders. 

For  these  reasons,  many  of  the  documents  selected  for  publication  from  the 
subject  folders  have  been  arranged  with  the  general  correspondence.  In  other 
cases,  where  information  would  be  lost  by  separating  the  selected  and  unselected 
material,  the  selected  items  have  been  retained  in  their  subject  folders.  However, 
closely  related  documents  found  in  multiple  subject  folders  have  been 
consolidated  into  one  folder.  In  some  cases,  the  folder  titles  have  been  modified 
slightly  in  the  editorial  arrangement  in  orderto  differentiate  between  the  vague  and 
repetitive  names  originally  given  to  them.  In  addition,  subject  folders  for  each  year 
appear  in  the  editorial  arrangement  immediately  following  the  general 
correspondence  for  that  year.  It  should  be  noted  that  there  is  still  considerable 
overlap  between  the  material  in  the  subject  and  general  correspondence  folders, 
and  both  should  be  used  in  conjunction. 

Numerous  subject  folders  consisting  entirely  of  documents  unrelated  to 
Edison  have  not  been  selected.  A  list  of  these  folders  appears  below.  In  addition, 
several  boxes  in  the  archival  record  group  have  not  been  selected:  boxes  25-27 
(War  Dept.  Ordnance  Bulletins  and  other  printed  material);  box  28  (photocopies 
of  correspondence  owned  by  Charles  Hummel;  see  Thomas  A.  Edison  Papers 
Digital  Edition,  X128C);  box  29  (photocopies  of  original  documents  filed  elsewhere 
in  the  record  group);  and  oversize  material.  A  finding  aid  for  the  record  group  is 
available  at  the  Edison  National  Historic  Site.

Naval  Consulting  Board  and  Related  Wartime  Research  Papers 
Correspondence  (1915) 

This  folder  contains  correspondence  and  other  documents  relating  to 
Edison's  role  as  chairman  of  the  newly  established  Naval  Consulting  Board. 
The  correspondents  include  Secretary  of  the  Navy  Josephus  Daniels, 
Edison's  chief  engineer  and  personal  representative  Miller  Reese  Hutchison, 
and  other  members  of  the  Board,  particularly  chemist  Leo  H.  Baekeland  and 
enqineer  Willis  R.  Whitney.  Included  are  items  pertaining  to  the  Board  s 
establishment  and  early  meetings,  the  appointment  of  its  members  from 
various  technical  societies,  the  formation  of  committees,  and  the  resignat  on 
of  Henry  A.  W.  Wood  in  December  as  a  result  of  his  disagreement  with  the 
defense  policies  of  the  Wilson  Administration.  There  is  also  material  regarding 
the  proposed  naval  research  laboratory,  including  Edison’s  personal  notes  on 
its  desired  specifications  and  a  16-page  memorandum  by  Whitney.  Among 
the  technical  subjects  discussed  in  the  documents  are  the  erosion  of  rifled 
barrels  in  heavy  artillery,  the  development  of  a  wire  cutting  projectile,  and  he 
absorption  of  hydrogen  gas  emissions  in  submarines.  There  are *  a  so 
numerous  unsolicited  letters  from  the  general  public  about  war-related 
inventions,  a  small  number  of  which  received  substantive  replies  from  Edison. 

Approximately  30  percent  of  the  documents  have  been  selected.  The 
unselected  items  consist  primarily  of  unsolicited  letters  relating  jo  the  jar  and 
ideas  for  weapons;  standard  replies  from  Edison  s  secretaries  stating  ‘hat  any 
inventions  submitted  would  be  forwarded  to  Board  secretary  Thomas  Robins, 
and  routine  correspondence  between  Robins  and  Edison's  personal  assistant 
William  H.  Meadowcroft,  regarding  the  transmittal  and  receipt  of  such 
materials.  Other  unselected  documents  include  routine  administrative  and 
organizational  papers  circulated  to  Board  members  and  an  essay  on  the 
proposed  naval  research  laboratory  by  Reginald  E.  Gillmor.

Hon.  ThomaB  A.Edison, 

East  Orange,  N.J. 

Dear  f^disoiu  intending  fQr  some  time  to  write  you  ex¬ 
tras  sinp  mv  admiration  at  the  splendid  and  patriotic 
Ittitudl  you  h£ve  tiken,  as  reported  in  the  public  press, 
in  refusing  to  devote  your  great  inventive  genius  to 
warlike  subjects  except  at  the  call  of  your  own  country. 

Such  an  attitude,  in  these  all  too  commercial  times,  is 
one  that  should  be  an  inspiration  to  our  young  men  and  a 
__n  in  the  ■oreeminent  right  of  onefs  own  country  to

natural  inventive  genius  of  Americans  to  meet  ^enew 
conditions  of  warfare  as  Bhown  abroad,  and it  is  my 
i n+ention  if  a  practical  way  can  be  worked  out,  asi 
think  it  can  be,  to  establish.at  the  earliest  moment  a 
department  of  invention  and  development,  to  which  all 

Irri 

sent  them  for  the  careful  study  required.  In  addition, 

br»5K^  s « assrss  z^^sr 


nor,  in  many  caaes,  the  natural  inventive  turn  of  mind 
needed  to  put  these  ideas  into  definite  shape.  Were  there 
a  place  where  they  could  he  sent  to  he  worked  out  and 
perfected,  I  am  sure  we  would  get  many  noteworthy  im¬ 
provements  from  this  source  alone.  We  have,  of  course, 
in  the  Navy  Department  energetic  and  wideawake  bureaus, 
headed  hy  experts  in  their  particular  lines  of  work  who 
devote  all  the  time  they  possibly  can  to  a  study  of  this 
problem.  They  have  made  important  contributions  to  the 
improvements  in  the  implements  of  naval  warfare  and  are 
dding  all  that  is  possible  with  their  other  large  duties. 
There  are,  unfortunately,  no  officers  now  detailed  who 
can  take  time  from  the  mass  of  work  which  they  are  called 
upon  to  do  in  order  to  devote  it  fully  to  studying  new 
suggestions  and  inventions.  The  Department  is  also  un¬ 
provided  with  the  best  facilities  for  work  of  pure 
experimentation  and  investigation,  with  the  exception  of 
our  testing  station  at  Annapolis,  which  is,  as  yet,  a 
small  affair.  Most  of  all,  as  I  have  said,  there  is  no 
particular  place  or  particular  body  of  men,  relieved  of 
other  work,  charged  solely  with  the  duty  of  either 
devising  new  things  themselves  or  perfecting  the  crude 
ideas  that  are  submitted  to  the  Department  by  our  natur¬ 
ally  inventive  people. 

I  have  in  mind  a  general  plan  of  organizing  such  a 
department  which  is  still  very  hazy  as  to  detailB  but 
which,  in  a  general  way,  meets,  so  far  as  the  Navy  is  con¬ 
cerned,  with  your  ideas  of  such  a  department  for  the 
Government  in  general.  I  want  to  use  such  facilities 
for  experimental  and  investigation  work  as  we  have,  under 
the  direction  of  men  particularly  selected  for  ability 
shown  in  this  direction,  to  whom  would  be  referred  all 
suggestions  of  new  devices  sent  in  to  the  Department  and 
who  would  work  out  such  ideas  to  a  practical  point.  Such 
a  department  will,  of  course,  have  to  be  eventually  sup¬ 
ported  by  Congress,  with  sufficient  appropriations  made 
for  its  proper  development,  although  I  feel  that  we  can 
make  a  start  with  the  means  at  hand.  To  get  this 
support.  Congress  must  be  made  to  feel  that  the  idea  is 
supported  by  the  people,  and  X  feel  that  our  ohanoes  of 
getting  the  public  interested  and  back  of  this  projeot 
will  be  enormously  increased  if  we  can  have,  at  the  start, 
some  man  whose  inventive  genius  is  recognized  by  the  whole 
world  to  assist  us  in  consultation  from  time  to  time  on 


matters  of  sufficient  importance  to  bring  to  his  attention. 
You  are  recognized  by  all  of  us  as  the  one  man  above  all 
others  who  oan  turn  dreams  into  realities  and  who  has  at 
his  command,  in  addition  to  his  own  wonderful  mind,  the 
finest  facilities  in  the  world  for  such  work. 

What  I  want  to  ask  is  if  you  would  he  willing,  as  a 
sertfice  to  your  country,  to  aot  as  an  adviser  to  this 
hoard,  to  take  such  things  as  seem  to  you  to  he  of  value 
hut  whioh  we  are  not,  at  present,  equipped  to  investigate, 
and  to  use  your  own  magnificent  facilities  in  such  investi¬ 
gation  if  you  feel  it  worth  while.  For  our  part,  we  will 
endeavor  not  to  bother  you  with  trivial  matters  as  we  will 
prohahly  have  sufficient  facilities  to  handle  such  small 
matters  as  they  come  up.  This  is  a  great  deal  to  ask  and 
I  unfortunately,  have  nothing  hut  the  thanks  of  the  Navy 
and,  I  think,  of  the  country  at  large,  together  with  the 
feeling  of  service  to  your  country  that  you  will  have,  to 
offer  you  hy  way  of  recompense;  yet, so  clearly  have  you 
shown  your  patriotism  and  your  unselfish  loyalty  to  your 
country’s  interests,  that  I  feel  Justified  in  making  this 

request. a^e  oonfrontea  wittL  a  new  and  terrible  engine  of 
warfare  in  the  submarine,  to  consider  only  one  of  the  big 
things  which  1  have  in  mind,  and  I  feel  sure  that,  with 
the  practical  knowledge  of  the  officers  of  the  Navy  with 
a  Department  composed  of  the  keenest  and  most  inventive 
minds  that  we  can  gather  together,  and  with  your  own 
wonderful  brain  to  aid  us,  the  United  States  will  be  able, 
as  in  the  past,  to  meet  this  new  danger  with  new  devices 
that  will  assure  peace  to  our  country  hy  their  effectiveness. 

If  you  feel  that  you  would  he  willing  to  do  this,  I 
would  like,  a  little  later,  when  my  plans  are  somewhat  more 
matured,  to  consult  with  you  as  to  the  details  of  the 
organization  proposed  so  that  I  oan  make  it  as  effective 
as  possible  for  the  purpose  intended. 

With  you,  it  might  he  well  to  associate  a  few  men 
prominent  in  special  lineB  of  inventive  researoh,  and  I 
would  like  also  to  consult  with  you  as  to  who  these  men 
should  he.  It  is,  of  course,  your  aid  that  I  rely  upon 
most  and  if  you  are  not  able,  for  any  reason  to  do  this, 

I  will  frankly  hesitate  to  undertake  the  matter  at  aix. 
Should  you  feel  like  accepting  the  task,  however,  I  know 
the  relief  which  the  country  would  feel  in  these  trying 


times  at  the  announcement  that  you  are  aiding  us  in  this 
all  important  matter. 

If  you  couia  let  me  know  as  early  as  you  may  how  you 
feel  about  this,  I  wouia  appreciate  it,  as  everything  waits 
upon  your  answer,  and  I  think  we  cannot  he  too  expeditious 
if  we  are  going  to  take  this  matter  up  at  all. 


Sincerely  yours.

Mr.  Edison: 

I  have  been  attJAgg-'automohileB  for  fifteen  years, 
and  am  what  might  he  considered  an  expert  driver.  Yet,  when 
I  take  hold  of  a  new  oar,  it  takes  several  dayB  and  sometimes 
a  week  to  so  master  its  idiosynoraoies  as  to  he  able  to  get 
the  host  there  is  in  it  out  of  it. 

!o  build  warships,  submarines ,  eto. ,  and  thei  put 
thorn  away  until  needed,  will  he  very  impraotioahle,  for  the 
reason  that  men  in  command  of  these  boats  and  the  men 
operating  turrets,  eto.  have  to  keep  oontainually  at  it,  in 
order  that  they  may  remain  proficient.  When  Daniels  took 
hold  of  the  Jtfavy  at  the  beginning  of  his  regime,  and  out  out 
battle  practice  the  ensuing  low  grade  of  morkmanship 
attested  the  point  I  am  raising.  Whereas,  under  the  former 
Administration,  target  praotloo  was  adhered  to,  this  Havy  in 
the  course  of  ten  or  twelve  years  gradually  ollmbed  to  the  top 
of  markmonship.  Ewo  years  of  comparative  idleness  dropped  us 
way  below  fourth  place. 

1  mention  the  above,  because  I  have  heard  a  great 
deal  of  adverse  oritioism  from  Havol  Offioors  regarding  your 
interview  with  Edward  Marshall,  advocating  building  boats  and 
then  putting  them  awey  for  use.  At  the  Brooklyn  Havy  Yard, 
they  all  say  they  are  sorry  that  you  advanced  this  suggestion. 


■because  it  is  sure  to  lessen  the  confidence  of  Haval  OffioOrs 
in  the  practicability  ,  of  the  storage  battery  $$kil  it  is 
proved  out.  Hon  they  accept  your  statement  that  the  battery 
is  practical,  at  full  valuo,  and  have  advised  accordingly. 
Those  who  know  still  have  the  same  idea,  but  it  has  been 
suggested  to  mo  that  I  ask  you  to  be  very  careful  about 
interviews  of  national  preparedness,  etc. 

A.  battleship  or  submarine  must  be  kept  in  eo.v$iA*a'nn 
and  hard  at  it  all  the  time,  to  enable  thoir  crows  to  obtain 
such  proficiency  as  will  enable  then  to  handlo  thoso  boats 
properly  in  an  engagement.  It  requires  skill  the  equal  of 
that  possessed  by  the  slight^flsand  performer  or  the  expert 
musician,  both  of  whom  have  to  practice  all  the  time  to  keep 
their  hands  in.

Dear  Sirs 

Your  favor  of  October  1st  has  reached  Mr.  Edison  with¬ 
in  the  last  day  or  two ,  having  been  addressed  to  him  at  Washing¬ 
ton,  which  was  incorrect. 

He  requests  us  to  say  to  you  in  reply  that  your  scheme 
could  be  demonstrated  by  using  a  pistol  and  making  an  actual  trial. 
There  is  very  little  doubt  that  it  will  work,  but  an  experiment 
on  a  small  scale  is  more  convincing  than  any  amount  of  writing • 

He  suggests  that  you  try  the  experiment  and  let  him  know 
the  result.

Dear  Mr .Edison:- 

Following  is  a  report  made  by  our 
laboratory  covering  experiments  on  the  absorption  of  hydro¬ 
gen  by  different  ohemioals.  None  seem  to  be  of  any 
particular  value. 

Kindly  advise  what  you  wish  done  further 


in  regard  to  the  matter.

The  Orsat  apparatus  was  used  in  all  parte  of  this  experiment 
The  hydrogen  was  obtained  from  #7  Building.  Each  part  of  t 
experiment  was  repeated  to  check.

Experimental  Absorption 
of  Hydrogen. 


AsbestoB  fibre  was  boiled  in  ferrous  sulfate  solution 
until  v/ell  saturated.  It  v/as  then  roasted  to  completely 
convert  the  HeS047H20  into  red  iron.  This  in  turn  waB 
reduced  by  Hydrogen.  By  this  process  ironized  asbestos  was 
obtained.  This  showed  a  small  amount  of  absorption  when 
warm, but  due  to  the  Hydrogen  held  by  reduction,  the  Hydrogen 
occluded  was  small.

Ur.  William  H.  Meadowcroft, 

Assistant  to  Ur.  Edison, 

Orange,  H.  J. 

Dear  Sir:- 

The  note  of  Ur.  Edison/fn  relation  to  the  absorp¬ 
tion  of  hydrogen,  has  my  full/at tent ion.  The  problem,  how¬ 
ever, is  not  an  easy  one.  / In  Niagara  Falls,  tw.e  have  to 
dispose  every  twenty- four  hours  of  one  ton  of  hydrogen  gas. 
But  this  offers  no  sepious  problem,  on  account  of  the 
exceptionally  high  ascensional  force. of  hydrogen. 

By  the  timsUr.  Edison  comes  back,  I  shall  be 
able  to  go  into  this  question  with  more  detail. 

Very  truly  yours.

IN  ANSWER  TO  YOUR  LETTER  OF 


subject:  Hydrogen  Absorption  for  Storage  Batteries. 

Mr.  Thomas  A.  Edison,  Chairman 
Naval  Consulting  Board, 

.  ..Orange,  N.  J.  • 

My  dear  Mr.  Edioon:- 


Bofore  you  left  for  the  Pacific  Coast, 
vou  were  kind  enough  to  send  a  note  to  me  on  the  desirabil¬ 
ity  of  finding  a  practical  way  for  absorbing  hydrogen  from 
the  air  in  submarines. 


I  note  what  you  say  about  the  possibility  of 
absorbing  by  permanganate  and  also  your  suggestion  of  util¬ 
izing  the  law  of  Graham,  relative  to  thediffuaionofsases, 
for  eliminating  the  hydrogen  through  unglazed  porcelain. 

it  occurs  to  me  that  the  latter  method  may  cease 
to  work  as  soon  as  the  porcelain  loses  ,, 

account  of  the  fact  of  it  becoming  wet.  In  Niagara  Falls, 
at  the  Hooker  Electrochemical  Company,  we  have  to. dispose 
of  a  ton  of  hydrogen  gas  per  day.  Up  till  now,  we  ^avenot 
utilized  this  hydrogen  and  simply  let  it  eBCaP® *  °°^noed 
of  the  possible  danger  of  such  large  amounts  of  hydrogen, 

I  requested  our  chemists  to  make  some  experiments  i 
determine  the  proportion  of  hydrogen  in  the  air  at  different 
points  of  the  cell -rooms,  which  are  made  of  reinforced  con¬ 
crete.  Without  going  into  the  details  of. the  analytical 
results,  I  might  state  that  I  was  very  much  impressed  by 
the  rapidity  with  which  this  hydrogen  ascends  and  mines 
with  the  air.  Quite  close  to  the  orifices  of. the  cells, 
we  find  almost  pure  hydrogen.  A  few  inches  above, the  hydro¬ 
gen  contents  of  the  air  have  become  very  Bmall,  and  near  the 
ceiling-.of  the  building,  the  amount  of  hydrogen  is  negligible. 

Of  course,  in  a  submarine,  conditions  are 
different,  beoause  there,  the  hydrogen  cannot  escape_ through 
wide  ventilators.  But  in  the  instance  of  Niagara  Falls,  I 

am  impressed -with  the  .fact  of  the  considerable  ascensional 
force  of  the  hydrogen,  which  in  the  case  of  a  submarine,^ 
ought  to  make  it  possible  to  collect  the  Sas  “of  a*7 

constructed  hoods  and  expel  it  mechanically  by J?  n  fhg 
rotary  pump  or  blower.  The  latter  could  be  used  when  the 
vessel  is  not  submerged,  while -the  rotary  pump  might  be 
neoessary  when  the  vessel  is  under  pressure.

Mr.  Edison.... #3.  Hov.  15,  3s IB. 

Instead  of  using  a  hood  for  collecting  the  hydrogen, 
it  might  be  much  simpler  to  conduct  the  gas  through  special 
piping,  from  where  it  could  be  disposed  of  further  by  means 
of  pumps  or  other  suitable  devices. 

Elimination  by  mechanical  means  seems  to  me  prefer¬ 
able  and  more  reliable  than  chemical  absorption  or  combustion. 
In  the  latter  case,  there  is  always  the  possibility  of  an 
explosion  in  case  something  goes  wrong.  Furthermore,  combus¬ 
tion  means  reduction  of  the  amount  of  oxygen  available  in  the 
air,  which  is  another  consideration  in  the  case  of  a  submerged 
vessel . 


I  discussed  the  matter  with  my  friend,  Mr.  Clinton 
Paul  Tov/nsend,  of  918  F  Street,  Washington,  D.  C.,  who  wrote 
me  the  following :- 

"Fou  are  undoubtedly  familiar  with  the 
J&ger  method  for  the  quantitative  determination  of 
hydrogen  in  presence  of .other  gases,  as  described 
for  example  in  the  Journal  of  the  Society  of  Chemi¬ 
cal  Industry,  December  SI,  1898,  page  1190,  and 
(Uhlig's  Modification)  February  38,  1910,  page  196. 
These  melfa  ode  depend  on  the  fact  that  copper  oxid 
will  oxidize  even  small  traces  of  hydrogen  at  rela¬ 
tively  low  temperatures  (350°  C.}. 

This  is  far  below  red  heat,  and  not  above 
the  usual  working  temperature  of  an  electric  radiator 
of  the  exposed  wire  type  such  as  is  often  used  in 
street  cars;  and  I  presume  that  similar  heaters  may 
now  be  used  in  submarines.  My  suggestion  would  be 
to  pack  these  heaters,  around  and  between  the  heat¬ 
ing  coils,  with  coarse  copper  oxid  (copper  scale), 
and  to  circulate  the  air  through  the  heated  copper 
oxid,  either  by  natural  or  forced  circulation. 

At  the  proper  temperature  there  should  be 
no  difficulty. in  oxidizing  even  traces  of  hydrogen  to 
water;  and  it  would  seem  also  that  there  should  be 
no  material  consumption  or. loss  of  the  copper  oxid, 
inasmuch  as  it  will  at  once  regenerate  itself  when 
the  hydrogen  has  disappeared,  it  being  necessary  for 
the  regeneration  only  to  pass  a  current  of  air  through 
it .  If  necessary  the  temperature  could  be  raised  at 
intervals  to  insure  regeneration. 

It  would  seem  as  if  a  submerged  vessel 
would  present  the  ideal  conditions  for  operating 
by  natural  circulation  of  the  air,  the  flow  being 
downward  around  the  cooled  walls  and  upward  in  the 
center.  If  the  heated  copper  oxid  were  placed  near 
the  top  of  the  arch,  as  indicated  in  the  accompanying 
sketch,  it  would  not  only  be  in  the  path  of  this 
natural  circulation,  but  at  the  point -where  the  con¬ 
centration  of  the  hydrogen -would  tend  to  be  at  a

maximum.  If  the  batteries  are 
in  a  closed  compartment  it  would 
seem  as  if  this  arrangement 
might  be  quite  effective,  while 
at  the  same  time  the  temperature 
of  the  copper  oxid  could  be  kept 
well  below  the  igniting  pBint  of 
any  mixture  of  hydrogen  and  oxygen. 

Of  course  if  desired  the  bat- 
'  teries  could  be  housed  in,  and  the 
gases  arising  from  them  circulated 
through  copper  oxid  at  the  proper 
temperature  by  a  fan. 

I  should  think  that  the  heating 
of  a  submerged  submarine  would  be  a 
decidedly  serious  problem;  and  this 
would  seem  to  afford  an  excellent 
opportunity  for  combining  the  opera¬ 
tion  of  heating  the  air  with  that  of 
freeing  it  from  even  traces  of  hydrogen. 

If  there  is  anything  in  this  sug¬ 
gestion,  you  are  entirely  at  liberty 
to  use  it  as  you  Bee  fit . 

Very  truly  yours, 

(Signed)  Clinton  P.  Townsend.  " 


I  answered  him  as  follows :- 


"I  thank  you  for  your  kind  letter  of  October 
36th.  On  Mr.  Edison's  return,  I  shall  submit  him 
your  suggestion.  _  , ■  • 

Although  304°  is  the  temperature  at  which  the 
ignition  of  hydrogen  would  not  occur,  I  fear  that 
under  certain  conditions,  when  the  amount  of  hydro¬ 
gen  is  large,  the  heat  developed  by  the  reaction 
will  carry  the  mass  beyond  304°.  There  are  many 
examples  where,  under  similar  conditions,  the  tem¬ 
perature  of  the  mass  increases  to  red  heat,  and 
then  the  possibility  of  ignition  and  explosion 
should  be  taken  into  consideration. 

Then  also,  if  electric  heating  is  used  for 
bringing  the  oxide  of  copper  up  to  reaction  tem¬ 
perature,  short-circuits  or  other  conditions  in 
the  electric  heating  system,  may  introduce  serious 
elements .of  danger.  I  am  so  much  the  more  under 
this  impression  since;,  a. few  days  ago,  one  of  my 
automobiles  was  set  afire  while  my  chauffeur  was 
working  on  it,  simply  on  account  of  a  small  spark 
caused  by  a  short-circuit. 

I  feel  that-  mechanical  removal  ought  to  be 
easier  and.  safer,  but  this  is  merely  my  personal 
opinion,  based  more  on  .intuition,  which  does  not

mean  to  say,  by  any  means,  that  your  suggestion 
could  not  be  carried  out  successfully.  My  opin¬ 
ion  is  mostly  derived  from  the  standpoint  that  I 
would  not  dare  to  take  chances  of  the  possibil¬ 
ity  of  a. hydrogen  explosion  in  a  submarine.  " 
(Signed)  L.  H.  Baekeland. 


I  bel  ieve  that  the  proper  solution  of  the  difficulty 
would  be  to  pipe  properly  the  storage  batteries,  so  as  to  con¬ 
duct  the  hydrogen  gas  where  it  can.be  handled  further  and  dis¬ 
posed  of  in  some  mechanical  way,  instead  of  letting  it  simply 
escape  in  the  air  and  diffuse,  as  now  seems  the  .common  practice 
among  storage  battery  manufacturers.

the  following  Besolution  was  passed: 

That  the  Chair  appoint  a  Committee  whose  iuty 
It  shall  he  to  draw  up  a  report  giving  all  the  arguments 
and  reasons  for  the  proposed  Eaval  Research  laboratory 
and  Experimental  Station,  to  report  to  the  Board  at  its 
next  session. 

I  beg  to  say  that  the  Chair,  exercising  its  function, 
has  appointed  thiB  Committee  as  follows: 

Mr.  Edison,  Chairman,  Dr.  1.  H.  Baekeland  and 

Dr.  W.  H.  Whitney. 

On  Mr.  Saunderfi'  suggestion  that  the  members  of  this 
Committee  may  obtain  some  suggestions  which  would  be  useful  in  the 
preparation  of  their  report  from  Admiral  Melville's  paper  which  is

an  Address  delivered  by  the  late  Rear  Admiral  Eelville  before  tne 
Engineers  Club  of  Philadelphia  in  relation  to  the  value  of 
experimental  investigation  and  researoh. 

If  this  publication  is  of  value  to  the  Kaval

or  from  the  Seo 'y-Treasurer  of  the  American  Society  of  Eaval  Engineers, 
Eavy  Department,  Washington,  D.  C. 

As  I  helped  Admiral  Melville  to  oollect  data 
for  this  monograph  I  know  that  the  address  represents  a  vast  amount 
of  investigation  and  3tudy.  The  address  commanded  the  attention  of 
Count  Reventlow  of  Germany  as  v/ell  as  of  the  xaculty  of  the 
Marine  Engineering  ana  Eaval  Architectural  Department  of  the 
Charlottenburg  and  other  German  experimental  laboratories. 

This  is  the  age  of  the  engineer,  ana  if  the 
counsel  and  advice  of  the  engineering  profession  will  be  welcomed  and 
sought,  then  national  preparedness  can  be  obtained  in  a  more  efficient 
and  less  costly  manner  than  by  any  other  means. 


The  faot  also  that  we  have  been  fellow

What  1b  the  matter  with  using  a  heated  platinum 
wire  inside  of  a  small  double  wire  gauze  cage  Bomewhat 
like  a  miner’s  safety  lamp?  This  platinum  should  cause 
oombuetion  of  the  hydrogen:  with  oxygen  of  the  air  end  the 
gauze  would  prevent  explosion  or  back  fire  and  also  permit 
esoape  of  the  water  vapor  formed.  This  reaotion,  whereby 
hydrogen  in  air  is  oxidized  in  oontaot  with  hot  platinum, 
is  a  very  complete  one.  Of  oourse  it  oonsumes  an  amount 
of  oxygen  equivalent  to  the  hydrogen  present,  but  doeB  not 
do  anything  else  harmful..  A  small  inoandesoent  lamp  in 
Beries  with  the  platinum  wire  would  indioate  that  the  appa¬ 
ratus  was  in  working  order-  While  this  outfit  might  be  put

Has  it  occurred  to  (yo^f^in^connect i o n^withi*the  problem 
which  has  been  submitted  to  us  by  the  Navy,  to  find  some  power  other  than 
compressed  air  for  driving  a  torpedo,  that.it  is  possible  to  very  largely 
increase  the  effective  work  of  a  definite  volume .of  compressed  airoy 
internal  heating  or  flaming  on  the  basis  of  the  old  Edisona^aiinde 
compressed  air  patents?— ^{js.cw>\^-aJCL.  iq-p-*a r'toA^y^^t?c^r^ ^  ,wv| 

You  ~ ha^^i^ned  a^flMnelwitMn  i 

compressed  air  chamber,  thus  expanding  the  air  through  heat  and  -reaching/ 
a  high  temperature,  the  products  of  combustion  remaining  within  the  air. 

We  were  not  able,  as  you  will  recall,  to  nullify  the  hurtful  effects 
from  these  products  of  combustion  when  discharged  underground  or  in^a 
closed  space.  Furthermore  there  were._dif £jcultie.s ,ab«”t  lubrication^ 
owing  to  the  high  temperatures. ^ 

In  a  torpedo  theA'^^o'^a^tval -  ...  _  . 

poisonous  gases  and  smoke,  and  in  view  of  the  t  empor Iry  use  and  subsequent 
destruction  of  the  apparatus  it  would  Beem  to  me  that  the  high  teinpeiature 
would  o«ou  »°  diffloultl...  ft.  tSilt&TZZZZ? 

I  doubt  that  anything  better  thin  compressed  air  c 
be  found  for  this  purpose  because  of  its  availability  and  simplicity. 

It  is  easily  stored  at  high  pressures,,  and  I  am  inclined  to  think 
that  the.  difficulties  . which  now.  exi st  are  mainly  due  to  the  fact  that 
the  volume  stored  becomes  insufficient  because  of  contraction  t.-j-ough 
cooling  and  of  the  other  difficulties  such  as  the  creation  of  moisture 
and  ice  when  cooled  by  pressure  reduction.  I  am  aware  that. a  method 
of  reheating  has  been  introduced,  but  I  do  not  understand  that  this 
method  carries  with  it  the.  enormous  enlargement  of  volume  which  the 
Edison-Saunders  system  gives  or  that  it  iB  in  any  degree  so  simple. 

The  reheating  might  be  done  in  a  chamber  located/ 
between  the  high  pressure  storage  chamber  and  the  engine.  Kerosene/ 
or  any  other  inflammable  material  might  be  used,  the  ignition  taking 
place  through  an  electric  spark,  and  when  once  ignited,  and, while  the.  j 
air  is  passing  from  the’  storage. tank  to  the  engine,  it. woul^^oe  impossible 
to  extinguish  the  flame.  In  one  of  my  experiments. I  placed// small,  V

Dear  Mr.  Saunders: 

Replying  to  your  favor  of  the  19th  instant, let 
rae  say  that  I  think  a  superheater  would  be  of  great  advantage, 
and  that  the  superheat  could  possibly  be  obtained  from  charcoal 
set  on  fire  eleetrieallyf»ith  Benzol  sprayed  in  below  the  ex¬ 
plosive  point.  She  Benzol  would  burn  and  heat  the  air  to  a  pre¬ 
determine  temperature.  She  charcoal  would  stay  lighted  contin¬ 
uously  through  out  the  whole  voyage.  Even  the  charcoal  might  not 
be  necessary  after  a  preliminary  momentary  ignition  by  an  elec- 
trie  wire  or  spark.  Superheat  is  well  worth  a  trial. 

Oh!  Shat  we  had  that  Laboratory.  Things  would 

move  quick.

I  have  just  finished  reading  the  confidential 
government  report  on  gun  erosion  and  believe  that  the  question  of 
thermal  conductivity  of  the  gun  metal  should  be  considered. 


Apparently  erosion  consists  of  the  sweeping  out 
by  the  gas  rush  of  a  thin  film  of  superheated  metal  and  it  has 
been  found  that  it  is  reduoed  by  using:

(b)  lower  maximum  temperatures  of  ha  combustion, 
(o)  gun  metal  of  higher  melting  point. 


Weight  of  projeotile  and  muzzle  velocity  seem  to  have  no  bearing 
and  small  scale  experiments  with  copper  gave  much  better  result b 
than  its  relatively  low  melting  point  would  indioat e,  but  plating 
the  bore  with  a  thin  film  of  copper  gave  negative  results. 


Kow  (a)  and  (b)  are  probably  identical,  as  a 
highly  compressed  gas  has  not  only  more  total  heat  units  per  unit 
of  volume,  but  probably  a  higher  thermal  conductivity  than  a  gas 
at  the  same  temperature  but  at  lower  pressure,  bo  that,  the  time 
interval  and  other  faotors  being  the  same,  the  metal  of  the  bore 
will  more  nearly  attain  the  temperature  of  the  gas  when  high 
pressures  are  used. 

Of  course  the  great  mass  of  the  gun  can  absorb 
many  heat  units  with  but  a  small  rise  in  temperature  and  the 
temperature  gradient  from  the  superheated  film  in  the  interior  of 
the  bore  deserves  study.  Y/ere.the  thermal  conductivity  of  the 
gun  metal  high  enough,  the  surface  film  could  be  kept  down  to  a 
temperature  which  would  resist  soouring.  This  idea  is  corroborated 
by  the  results  with  oopper,  the  notably  high  thermal  conductivity  or 
7/hioh  more  than  offset  tfte  low  melting  point  when  the  metal  was  used 
in  sufficient  mass,  and  doubtless  explains  why  various  alloy  steels 
gave  paorer  results  than  those  more  closely  approaching  pure  iron. 


The  practical  point  of  all  this  is  that  we  know 
that  mere  traoes  of  certain  impurities  have  enormous  effects  upon 
the  electrical  conductivity  of  copper  and  by  analogy  it  is  quite 
possible  that  minor  changes  in  the  composition  of  the  alloy  might 
have  surprising  effects  upon  the  thermal  conductivity  of  gun  metal. 
Elements  like  E.  Si  and  A1  I  have  particularly  in  mind. 


I  would  therefore  suggest  that  some  measurements  of 
the  thermal  conductivity  of  some  of  the  gun  metals  actually  used 
might  advantageously  be  made  and,  if  a  relation  seemed  established 
between  erosion  and  conductivity,  the  subject  could  be  followed 
systematically  to  a  practical  conclusion.

Oct.  8th.  ,  1915. 

Hon.  Josephus  M.  Daniels, 

Secretary  U.  P.  Navy, 

Washington,.  D.  C. 

Sir:- 

May  I  offer  a  suggestion  as  to  possiblo  means  for  expedit¬ 
ing  the  labors  and  perhaps  increasing  the  efficiency  of  the  Con¬ 
sulting  Board  which  you  are  forming  —  which  bo:ard  will  be  the 
greatest  “Inventing  Machine"  ever  assembled’ 

You  are  contemplating  the  provision  of  .a  research  labora¬ 
tory  to  try  out  the  suggestions  of  these  experts;  but  has  it  ooour- 
ed  to  you  to  furnish  your  inventors  with  the  services  of  an  expert 
who  could  supply  them  in  advance  with  a  comprehensive  and  complete 
review  of  the  suggestions  of  all  other  thinkers  along  the  line 
which  they  are  for  the  time  being  to  investigate?  This  question 
applies  in  particular  to  the  disclosure  of  the  Patent  Office  records, 
for  you  will  have  on  your  Board  experts  familiar  with  all  cr  a  major 
portion  of  the  literature  on  the  subjects  investigated. 

In  this  connection  it  should  be  remembered  that  the  subjects 
matter  of  the  patents  of  the  United  States,  which  are  now  rapidly 
approaching  a  million  and  a  quarter  in  number,  and  of  all  the  pat¬ 
ents  issued  in  foreign  countries  which  number  about  the  same,  are 
impossible  of  exhaustive  knowledge  by  any  man  or  association  of 
m0n.  That  even  the  experts  of  the  Patent  Office,  whose  labors 
often  for  a  period  of  years  are  confined  to  their  own  special  line 


[ATTACHMENT/ENCLOSURE] 


#2. 

of  invention,  are  not  so  familiar  wdth  their  olas6es  tie  to  attempt 
to  pass  on  an  application  far  patent  without  a  search  with  that 
particular  invention  in  mind.  It  may  therefore  be  oonceded  that 
your  Board  as  a  whole  will  be  unfamiliar  with  the  majority  of  the 
suggestions  of  prior  inventors  on  any  subject  which  they  take  up. 

The  question  then  is:  ’Jill  a  ocmplete  review  of  the  efforts 
of  earlier  inventors  to  solve  the  problem  in  mind  be  of  use  to 
suoh  a  Board  as  the  Navy  Department  has  oreated?  It  would  seem 
that  in  a  majority  of  oases  the  answer  must  necessarily  be  "Yes". 
While  it  is  of  couroo  true  that  a  large  percentage  of  the  patents 
issued  are  on  more  or  less  impracticable  and  visionary  schemes, 
yet  in  numberless  instances  these ^schemes ,  impracticable  as  they 
are,  embody  the  germ  of  a  good  idea  which  experts  could  modify  or 
employ  in  principle  to  develop  a  feasible  construction.  In  o- 
ther  instances  the  devices  may  have  been  practical  and  in  fact 
have  come  into  seme  considerable  use  and  still  have  escaped  the 
notioe  of  those  who  may  be  olaosed  as  experts  in  the  art  to  which 
they  relate.  In  still  other  oases  the  idea  may  have  been  appar¬ 
ently  feasible  and  might  again  occur  to  your  Board  as  good  but 
still  have  had  some  latent  objection  whioh  oould  be  discovered  by 
an  investigation  into  the  history  of  the  invention.  In  all  of 
these  cases  it  would  apparently  be  of  great  aid  to  the  labors  of 
the  Board  if  it  were  fully  informed  in  advance  as  to  what  had  been 
suggested  by  others  in  order  that  its  labors  and  investigations 
need  not  retraverse  already  explored  territory. 


[ATTACHMENT/ENCLOSURE] 


#3. 

Thera  is  another  way  in  which,  in  ray  opinion,  an  expert 
suoh  ae  I  have  suited,  familiar  with  the  rather  complex  and  in¬ 
tricate  classification  of  patents  in  the  Patent  Offioe  could  he  of 
assistance  to  the  Board.  In  the  solution  of  problems  submitted 
to  it  and  in  devising  means  of  meeting  these  problems,  there  will 
in  many  instances  be  re-invented  expedients  old  to  other  artsjwhich 
expedients  are.  oapablo  of  being  carried  over  into  the  new  situation 
either  unchanged  or  modified  to  suit  the  new  conditions,  without 
the  laborious  prooeding  of  reconstructing  them  to  meet' the  require¬ 
ments  at  hand.  In  such  oases  before  the  very  valuable  time  of 
the  inventive  geniuses  of  the  Board  were  taken  up  with  a  problem, 
would  it  not  be  well  to  submit  it  as  a  demand  to  be  met  to  a  pat¬ 
ent  expert,  to  determine  if  in  other  lines  this  same  problem  or 
an  analogous  problem  had  not  been  encountered  and  solved?  An 
experience  with  patents  extending  over  almost  fifteen  years,  both 
within  the  Patent  Office  and  as  an  attorney  in  patent  matters,  has 
impressed  ver^  strongly  on  me  the  uselessly  large  number  of  times 
that  substantially  the  same  idea  is  re-invented  to  meet  either  the 
same  or  analogous  requirements.  All  labor  of  re-invention  is  ob¬ 
viously  wasted  and  new  thought  in  any  field  should  evidently  begin 
where  others  have  left  off  instead  of  having  first  to  retraoe  the 
steps  of  other  inventors. 

The  utilization  of  knowledge  as  to  what  prior  patents  dis¬ 
close  along  a  given  line  is  not  new  for  most  of  the  larger  corpor¬ 
ations  make  a  practice  of  keeping  their' inventors  fully  informed 
as  to  all  developments  in  their  line.  I  am  told,  and  see  no  reason 


[ATTACHMENT/ENCLOSURE] 


#4. 

for  doubting  it,  that  Mr  Edisons  first  step  in  approaching  a  now 
problem  is  to  have  laid  before  him  oomplete  information  as  to  ev¬ 
erything  thut  has  been  suggested  to  meet  the  problem  not  only  in 
the  patents  but  also  in  the  literature  of  the  art.  In  fact  it  is 

hard  to  see  how  inventors  can  efficiently  operate  in  any  other 
manner.  But,  so  far  as  I  know,  I  am  the  first  to  see  the 

possibilities  of  what  may  be  termed  "ancillary  investigation"  of 
the  Patent  Office  files;  a  systemmatic,  advanoe  investigation  for 
the  purpose  of  obviating  .reinvention  in  a  particular  instance  of 
constructions  whioh  may  as  well  be  carried  over  from  another  art. 

A  search  to  meet  a  demand ;-.vhich  should  be  as  complete  and  exhaus¬ 
tive  as  validity  searches  now  are  —  and  I  may  say  that  the  major¬ 
ity  of  validity  searches  end  in  a  demonstration  that  the  idea  wao 
not  new.  ’  1  have  recently  carried  on  some  investigations 
along  this  line  for  manufacturer  clients  with  very  gratifying  re¬ 
sults  and  I  believe  that  the  Department  can  well  avail  itself  of 
some  such  service. 

The  employment  of  a  patent  expert  by  a  department  of  the 
Government  is  not  without  precedent  for  about  ton  yearB  or  so  ago 
the  Census  Bureau  omployed  such  services  in  what  was,  if  I  remem¬ 
ber  oorreotly ,  a  successful  attempt  on  the  port  of  the  Bureau  to 
devise  tabulating  machinery  whioh  should  not  be  subject  to  royalty 
under  what  were  then  supposed  to  bo  patents  dominating  their  field.

Dear  Sir: 

I  am  in  receipt  of  your  favor  of-  the  ninth  instant. 

I  think  you  have  not  quite  understood  the  position  that  the 
Haval  Consulting  Board  occupies,  although  the  newspapers  have 
published  it  broadcast.  For  your  information  I  would  say  that 
the  Board  is  an  Advisory  board,  and  not  a  Board  of  Inventions. 

At  the  Libraries  of  the  various  Engineering  Societies 
there  is  usually  kept  a  most  voluminous  card  index  system  in 
which  about  everything  known  in  engineering  lines  is  indexed, 
and  if  a  member  wants  information  relating  to  an  engineering 
subject,  he  can  get  what  ho  watns  at  a  very  low  rate.  I  am  not 
aware  whether  or  not  all  patents  are  indexed  in  like  manner,  but 
1  think  so.  Cbus  it  is  already  possible  to  carry  out  your 
suggestion  which  I  am  free  to  Bay  iB  a  very  good  one.

Dear  Mr.  Edison: 

I  am  sending  you  today  a  revised  suggestion 
for  a  report  to  our  Hagai  Consulting  Board.  As  we 
were  ashed  only  for  "arguments  and  reasons",  I  have 
finally  omitted  all  other  considerations ,  such  as 
proper  buildings,  equipment,  personnel,  etc,  but  have

The  arguments  and  reasons  for  a  naval  re- 
searoh  laboratory  were  well  presented  by  Melville  in 
1903  and  the  last  twelve  years  have  emphasized  the 
needs-  The  navy  is  larger,  the  complexity  is  greater 
anfyforeign  advances  have  been  enormous.  Our  con¬ 
ception  of  a  suitable  researoh  department  inoludes  a 
laboratory  proper,  msohinc  shop,  foundry,  forge,  shop, 
eto.,  suffioient  in  themselves  to  permit  of  rapid  pro¬ 
duction  of  the  first  unit  of  many  of  the  naval  aooessories. 
The  first  working  model  of  any  piece  of  apparatus  usually 
requires  the  closest  attention  of  the  interested  engineor. 
Changes  in  design  during  the  construction  period  are  very 
desirable.  Eoonomies  in  such  work  are  most  easily 
introduced  during  the  early  stages-  The  personal 
interest  is  greatest  when  the  meohanioal  part  does  not 
trail  too  far  behind  in  time  or  too  remote  in  poBitlfin 
from  the  person  most  interested.  It  is  for  thi s  repson 
that  the  entire  meohanioal  and  personal  outfit  whioh  has 
to  do  with  the  production  of  the  first  unit  of  a  naval 
accessory,  should  be  oomplete  and  oompaot,  cooperative 
and  coordinated.  This  1b  a  condition  so  entirely  foreign 
to  the  oustom  of  our  Navy  that  the  idea  appears  to  be  re¬ 
pellent  to  some  of  the  practical  men  from  its  mere  novelty.

Admiral  Melville  Jointed  out  that  the  establishment 
of  a  suitable  researoh  laboratory  would  oost  but  little  moro 
than  the  annual  loss  by  "oorrosion  mishaps  and  depreciation 
of  military  applianoes  of  two  of  these  floating  fighting 
machines".  I  qu6te  from  the  address  a  few  portions  which 
still  bear  with  particular  stress  twelve  years  after  they 
were  written: 


[ATTACHMENT/ENCLOSURE] 


"The  rise  of  Germany  as  a  naval 
and  maritime  power  daring  the  past 
thirty  years  has  surprised  the  world. 

1  believe  that  her  battleships  for 
their  tonnage  are  the  best  afloat***. 

** *■*'"* ‘Strangest  of  all,  this  ex¬ 
cellence  in  the  construction  of  war¬ 
ships,  as  well  as  in  the  building  of 
vessels  for  the  ooean-going  trade,  is 
not  the  result  of  a  progressive  series 
of  failures, either  in  design,  construction, 
or  of  operation. 

"The  suooess  of  Germany  oan  be  ao- 
oounted  for  only  by  recognizing  the  faot 
that  study,  reflection,  and  reseBroh  must 
have  been  expended  in  the  preparation  of 
plans,  in  the  building  up  and  the  organ¬ 
ization  of  the  shipyards,  and  in  laying 
out  and  carrying  on  the  work  of  oonatruotion. 
It  was  tho  high  appreciation  of  the  value  of 
original  investigation,  ooupled  with  experi¬ 
mental  work,  that  has  oaused  Germany  to  ad¬ 
vance  progressively  and  successfully’.’"

"For  over  a  hundred  yearQ  Germany, 
as  a  nation,  has  oarried  on  more  orig¬ 
inal  researoh  along  teohnioal  lineB 
than  any  other  power.  While  it  is 
true  th^t  both  England  and  Amerioa 
have  put  to  praotioal  application  the 
principles  discovered  by  German  re¬ 
searoh,  thereby  gaining  commercial 
and  maritime  advantages,  it  has  been 
the  Teuton  who  has  sought  after  principles.* 
"In  a  desultory  and  sporadio  manner 
all  naval  powers  have  done  some  experi¬ 
mental  work.  It  is  because  original 
investigation  is  not  always  appreciated 
in  its  fullness  by  the  Anglo-Saxon  that 
many  administrative  exeoutive  offioers 
are  indifferent  to  Buoh  researoh,  and 
therefore  experimental  tests  in  Great 
Britain  and  America  are  not  always  of  a 
oontinuingf&ature.  Great  Britain,  however. 
haB  reoently  been  compelled  to  establish  a 
National  Physioal  laboratory,  because  the 
encroachment  of  continental  rivals  threat¬ 
ened  to  interfere  with  her  foreign  markets."

purposes,  sinoe  both  tho  cost  of  construction

under  his  oontrol  had  been  reduoed  as  a  re¬ 
sult  of  the  data  Beoured  from  experimental 
work.  There  is  not  a  leading  university,

"The  primary  reaBon  Bnd  ohief  objeot 
for  establishing  the  laboratory  is  to 
inarease  the  effioienoy  of  the  naval 
service  by  preventing  the  adoption  on 
our  ships  of  war  of  untried  or  doubt¬ 
ful  devioes  and  expedients. 

"Sinoe  it  is  the  aim  of  many  pro¬ 
moters  to  foroe  their  wareB  upon  the 
government,  every  executive  department 
should  have  at  its  command  a  laboratory 
or  a  station  where  extended  tests  oould 
be  made  for  determining  the  valuo  Bnd 
usefulness  of  every  applianoe  submitted 
for  adoption. 


"The  experimental  station  would  like¬ 
wise  be  veluable  for  a  proposed  post¬ 
graduate  course  in  engineering.  This 
work  is  ss®  essential  to  naval  effioienoy, 
and  is  earnestly  desired  by  many  junior 
bffioerB  of  the  Borvioe-  Post-graduate 
work  in  engineering  has  been  recommended 
by  the  Academic  Board,  for  this  advanoed 
work  is  absolutely  neoessary  to  seoure

that  will  be  needed  in  the  hear  future. 

If  the  laboratory  will  help  to  provide 
for  this  supply,  its  establishment  will 
be  alone  Justified  by  giving  euoh  ex¬ 
perts  to  tho  navy." 

He  also  pointed  to  the  importance  of  develop¬ 
ing  local  discovery  as  distinot  from  purchasing  ideas 
already  generally  made  publio.  This  would  be  possible 
in  a  naval  research  laboratory.  It  has  been  the  hiB- 
tory  of  some  of  our  useful  naval  apparatus  that  it  hflB 
been  hawked  about  the  world  for  years,  until  recognition 
of  its  value  by  others  has  foroed  us  to  aooept  it. 

The  words  of  our  most  experienced  naval  ex¬ 
pert  are  truer  today  than  ever  before.  It  might  be 
sheer  presumption  on  our  part  to  add  to  his  expressions. 
I  feel  that  in  attempting  to  add  to  the  pioture  of 
government-need  whioh  be  painted,  I  am  continuing  but 
feebly  what  ho  himself  started,  and  ora  doing  it  merely 
to  bring  his  wort  up  to  date. 

In  a  list  of  twenty-five  naval  problems  whioh 
he  prepared,  in  order  to  illustrate  what  a  laboratory 
should  undertake,  there  is  muoh  food  for  thought,  and 
in  problems  born  slnoe  then  there  is  at  least  as  muoh 
more.  He  spoke  of  the  determination  of  the  value  of 


[ATTACHMENT/ENCLOSURE] 


liquid  fuels  for  ezines  and  toilers,  and  much  has  teen 
done  with  oil  and  gasoline  since  1903,  tut  we  are  still 
struggling  with  the  foreign  Diesel  engine  teoause  no 
suitable  American  type  exists-  *Ma  work  is  certainly 
not  oompleto.  It  woo  never  more  highly  desirable. 

He  spoke  of  the  possibilities  of  steam  turbines  for 
installation  in  worships,  and  you  know  the  active  state 
of  that  field  today.  He  spoke  of  the  relative  value 
of  different  alloys  for  machinery  purposes  and  the  more 
extensive  uso  of  steel  oastlnge.  etc.,  etc.  Since  that 
address  probably  more  now  elloys  hove  been  made,  outside 
of  the  liavy,  than  in  any  previous  twelve  years  of  the 
world •  Steel  oaetlngs  made  in  lorgo  and  in  small 
batches  have  boon  commercially  poured  for  several  years 
from  electrio  furnnoes,  where  experiments  on  composition, 
temperature,  etc.,  are  muoh  simpler  than  ever  before.  He 
showed  by  this  list  that  he  wanted  to  keep  the  Havy  abreast 

of  or  ahead  of  the  times. 

How  what  did  he  omit  from  the  list  whioh  I  am 
willing  to  point  out?  It  is  the  unforeseen  needs,  the 
new  knowledge,  the  things  ho  knew  researoh  would  develop 
hut  whioh  oould  not  then  be  even  called  by  name.

In¬ 


festing  an*  untried  art!  doubtful  devloes  he 
oonsldered  to  be  the  primary  reason  and  ohlef  objeot 
of  a  laboratory,  and  while  that  alone  1b  reason  enough 
for  very  much  greater  laboratory  faollltlcB  than  our 
Havy  poBBoBaes,  still  a  testing  laboratory  1b  only  part 
of  a  researoh  laboratory,  and  thle  he  recognized  per¬ 
fectly.  Where  are  to  wrg  originate  the  Bpeoial  de¬ 
vices  to  be  tested  and  which  we  so  sorely  need?  Shall 
we  oopy  from  other  countries  and  trail  behind  them? 

Shall  we  depend  entirely  upon  tho  fortuitous  discoveries 
of  our  people,  who  must  of  necessity  be  only  scantily 
supplied  with  a  knowledge  of  navy  needs  (the  real  re¬ 
quirements)  and  poorly  equipped  for  extended  research? 
Without  having  seen  the  letter  files  of  the  Havy,  I  think 
It  Is  safe  to  say  that  ninety-nine  peroent  of  all  the 
civilian  plans  presented  to  the  Secretary  are  not  worth  • 
even  a  laboratory  test-  The  Inventors,  If  they  were 
familiar  with  the  actual  foots  relevant  to  their  plans, 
a  little  better  trained  in  soienoe  and  more  oonversant 
with  the  relatively  advanoed  state  of  naval  arts,  might 
put  their  mental  efforts  to  valuable  use,  but  at  present 
there  is  no  preparedness  for  naval  invention.

let  me  illustrate:  Admiral  Melville’s  long 
list  of  Havy  needs  includes  no  refcronoe  to  wireless, 
nor  to  any  one  of  its  multitude  of  accessories ,  to 
detecting  or  locating  invisible  submarines  or  ways  to 
trap  or  destroy  them.  nothing  is  saia  about  the  aero¬ 
plane  nor  of  the  problems  in  aeronautics  and  aero  motors. 
There  are  no  aero  torpedoes.  Ho  reference  is  made  to 
aero  guns,  nothing  is  said  about  lighting  the  sea  at 
night,  neither  by  searchiight  nor  by  star  bombs.  Nothing 
is  said  about  electric  drive  nor  eleotrio  control.  The 
gyrosoope-oompass  and  gyro-torpedo  are  not  mentioned,  nor 
are  the  very  desirable  range  finders  and  periscopes.  There 
are  more  naval  novelties  today  than  there  were  known  prob- 
lens  then.  A  question  as  to  a  suitable  wire  for  a  wire¬ 
less  antenna  on  shipboard  would  have  been  but  an  inoorgnnity 
of  contradictory  words.  Therefore  we  want  to  emphasize 
the  fact  that  to  prepare  for  naval  defenoe  we  muBt  have  a 
good  dar  open  to  the  newly  developing  needB  of  the,  Havy,  a 
good  eye  on  the  advancing  scientific  work  of  the  world,  and 
a  good  hand  in  it. 


[ATTACHMENT/ENCLOSURE] 


I  do  not  claim  that  the  erection  of  laboratory 
buildings  and  the  employment  of  a  few  trained,  research 
men  will  at  onoe  revolutionize  the  war  industry,  or 
better,  peace  industry-  But  1  know  of  no  more  direct 
way  of  doing  exactly  what  1  think  needs  to  be  done. 

Most  of  the  known  Havy  problems  are  already  highly  spec¬ 
ialized.  Probably  most  of  the  future  ones  will  be 
along  still  more  highly  specialized  lines.  The  naval 
commanders  of  the  fleet  must  'phono  by  wirelesB  freely 
and  easily  to  one  another  at  all  times  and  yet  not  be 
heard  on  onem$  ships.  The  submarine  of  the  enemy 
will  be  seen  or  heard  miles  in  the  distance.  The  on¬ 
coming  torpedo  will  probably  be  prematurely  exploded  at 
a  distanoe  and  many  other  things  will  be  done  not  dreamt 
of  in  our  present  philosophy.  Most  of  this  will  not 
be  d6ne  by  the  typioal  ingenious,  but  impoverished  Yankee 
working  a  few  weeks  in  the  woodshed  on  the  farm,  nor  yet 
by  the  mentally  active  bank  president  of  the  city.  It 
will  have  to  be  done  by  the  highest  trained  specialists 
the  oountry  can  produce.  I  think  it  oan  all  be  done 
by  direct  scientific  application.

•Vh 

Many  of  the  new  problems  of  naval  defence 
and  many  of  the  suggestions  likely  to  be  made  oould 
be  undertaken  in  a  laboratory  not  very  different  from 
the  one  at  Schenectady.  Experiments  on  submarines 
and  aeroplanes,  on  steam  boilers  and  motors,  must  evi¬ 
dently  bo  tried  under  water,  in  the  air,  and  on  a  large  ' 
scale,  but  most  of  the  fundamental  experimental  work  can 
be  done  in  a  laboratory.  In  some  such  central  organ¬ 
ization,  work  of  one  field  is  oortain  to  have  a  bearing 
on  others  and  must  gradually  build  up  a  stock  of  exper¬ 
ience  and  kno7/ledgo  whioh  may  be  widely  applicable.  The 
Schenectady  laboratory  illustrates  this.  In  the  work 
on  alloys,  whioh  began  with  transformer  steels,  the  pro¬ 
cess  of  Calorizing  has  been  tested  with  various  metals. 

In  the  case  of  iron  it  has  been  found  useful  in  greatly 
raising  the  temperature  whictylron  will  stand  in  air.  It 
is  being  tried  in  boiler  tubes.  Calorized  copper  con¬ 
denser  tubes,  under  the  severe  oonditionB  of  Uew  York  and 
Boston  harbors,  have  now  been  in  successful  use  between 
three  and  four  years.  These  are  mentioned  beoause  they 
are  both  naval  problems.  In  connection  with  studies  of 
inoandescent  lamp  phenomena  we  had  to  study  thermionic

emission  and  we  Boon  found  ourselves  In  wireless  fields. 
Similarly,  wireless  generators,  reoeivers,  rectifiers, 
and  emplifiers  have  all  been  made,  frequently  because 
of  their  bearing  on  something  else,  so  that,  thru  oon- 
oomitent  incidents,  we  oould  today  fit  out  a  fleet  with 
±wireless  telephone  apparatus-  V7e  are  making  metallic 
magnesium  and  sdarchllght  oarbons,  and  we  oould  under¬ 
take  studies  in  sea  illumination  or  aerometals  at  onoe. 

It  is  for  these  reasons  that  I  would  be  satisfied  to 
leave  to  future  developments  the  welfare  of  a  naval  re¬ 
search  laboratory  if  the  establishment  on  a  firm  basis 
and  a  guaranteed  life  of  ten  years  oould  be  insured. 

It  has  been  suggested  that  the  facilities  of 
our  oommeroial  manufacturing  plants  and  laboratories  be 
called  upon  to  help  naval  research  and  that  existing  bureaus 
of  the  government  do  the  work.  This,  as  an  assistance, 
seems  well  worth  while.  3ut  it  should  be  organized  and 
hhe  problems  pushed  from  a  central  aotive  organization. 

It  oould  inolude  assistance  from  many  of  our  college  and 
teohnioal  school  laboratories,  but  would  be  terribly  slow. 

It  is  not  oonoeivable  that  suoh  a  oofirdinationn  of  different 
plants  would  be  a  suitable  substitute  for  a  oentral 
organization  where  oontinual  study  and  effort  would  be 
expended  to  improve  Havy  apparatus.

Briefly,  then,  there  are  25  naval  problems 
suggested  by  Admiral  Melville  ana  thirteen  additional 
suggested  by  Secretary  Daniels.  Most  of  those  could 
be  better  studied  by  an  organisation  under  naval  con¬ 
trol  than  otherwise.  Any  ohe  of  thorn  would  warrant 
some  onrefxil  study  ana  many  of  them  should  reooive  a 
great  deal-  They  sufficiently  warrant  a  laboratory, 
but  they  are  not  the  only  warrants-  A  leading  navy 
must  evolve  or  adopt  new  devices-  This  necessity  never 
ceases.  X  believe  the  useful  possibilities  are  greater 
in  research  along  novel  naval  lines  than  along  those 
lines  devoted  mostly  to  small  increases  in  efficiency 
of  existing  apparatus.  For  example,  X  thin*  good 
practical  research  work  on  Admiral  Fiske's  wireless 
dirigible  torpedo  launched  from  an  aeroplane  would  be 
more  efficient  than  equal  effort  spent  on  the  corrosion 
of  boiler  tubes-  One  may  be  colled  a  flying  start 
and/othor  a  start  from  standstill.

thrown  out  and  the  rapid  reverse  thrown  in  which  would  oarry  the  tool 
holders  up  above  the  work  and  then  the  chuck  carrier  would  rotate 
around  to  its  next  position  and  the  tool  carrier  would  Btart  downward 
again.  In  doing  the  work  on  most  shells  it  would  he  advisable  to  have 
the  machine  set  so  that  It  would  work  on  four  pieces  while  the  operator 
would  take  out  two  pieces  and  put  in  two  more  and  the  machine  would 
index  two  spaces  instead  of  one.  I  have  the  tooling  laid  out  for 
making  3"  shells.  If  you  would  he  interested  in  receiving  this,  I 
would  he  glad  to  mail  you  blue^ptintB  covering  same.  This  machine  has 
not  been  built.  All  I  have  is  a  complete  set  of  working  drawings. 

These  drawings  have  been  shown  Jo  different  engineers  who  are  engages  in 
th^^chine  tool  business  and  they  think  very  well  of  same,  that  it  is 

a  very  simple  design  considering  what  it  will  do  and  that  it 


will  work.

EDI SOU,  Esq., 
Orange, 


My  dear  Ur.  Edison:- 


C 


It  is  with  profound  regret 
that  I  tender  you  my  resignation  as  a  member  of 
the  ITaval  Consulting  Board.  I  have  been  compelled 
to  do  this  because  I  cannot  on  the  one  hand  con¬ 
scientiously  withhold  my  protest  against  the  wholly 
inadequate  defensive  plans  of  the  Administration, 
nor  on  the  other  hand  make  my  protest,  as  I  am 
conscientiously  bound  to  do,  and  remain  a  member 
of  your  distinguished  body  without  stibjeoting  the 
latter  to  severe  criticism. 

This  being  so,  and  notwithstand¬ 
ing  that  my  action  has  required  of  me  the  greatest 
sacrifice  that  I  have  ever  had  to  make, —  that  of 
surrendering  one  of  the  highest  honors  that  can  come 
to  an  American  -  I  have  been  unable  to  see  my  duty 
in  any  other  light  than  that  above  expressed. 

I  believe  that  we  are  facing 
the  greatest  crisis  that  we  have  known  since  the 
Civil  War  and  that  upon  our  actions  in  the  present 
will  depend  not  only  the  future  welfare  of  our  people, 
"but  our  continuance  as  a  first  class  power*  .therefore 
I  cannot  permit  such  a  mishandling  of  our  defenses 
as  the  Administration  proposes  without  striving  with 
all  ray  might  to  prevent  it.  This  I  am  conscious  will 
carry  me  into  a  period  of  bitter  controversy,  but 
whatever  its  costs  I  mean  to  push  this  controversy 
to  the  end,  regardless  of  whomsoever  it  may  tort, 
myself  included. 

I  cannot  withdraw  from  among 
my  recent  associates  without  an  expression  of  the 
warmth  of  affection  for  the  members  of  the  Naval 
Consulting  Board  which  I  have  already  experienced, 
and  particularly  for  yourself  whom  I  have  revered 
if  I  may  say  so  frankly,  above  all  other  men  as  the 
greatest  philanthopist  the  world  has  ever  known.

Uy  dear  Ur.  Wood: 

Your  favor  of  the  22nd  instant  was 
received,  and  read  withTJ.gr eat  deal  of  regret. 

I  am  sorry  that  you  feel  compelled 
to  resign  from  the  membership  of  the  Haval 
Consulting  Board.  We  shall  all  miss  the  ad¬ 
vantage  we  might  have  derived  from  having  you 
with  us.

Dear  Sir: 


PROJECTILE  FOR  USE  AGAINST  WIRE.  AIRCRAFT  etc . 
I  have  the  pleasure  to  acknowledge  receipt  of  your  valued 


favour  of  the  23rd,  Inst. 

Regarding  my  invention  I  beg  to  say  that,  after  many  prelim¬ 
inary  tests  of  my  device,  in  miniature .with  results  that  warranted 
the  outlay,  I  have  made  a  working  model  in  steel,  for  a  caliber 
of  approximately  75  m/m,  or  say  about  3  inches. 

Subject  to  some  slight  technical  modifications  this  model 
typifies  the  projectile  as  it  would  be  made  for  actual  use  against 
wire  entanglements  or  aircraft  in  war;  and  I  should  be  gratified 
if  I  could  have  an  opportunity  of  shewing  it  to  Mr.  Edison. 

I  expect  to  be  in  New  York  on  the  28th,  Inst.,  and  shall  bring 
along  the  model. 

Please  inform  me  whether  it  will  be  possible  to  meet  Mr.  Edison 
there . 

Faithfully  yours. 


Deo.  27th.  1915. 


hear  Admiral  Joseph  Strauss,  U.  S.  II., 

Chief,  Ordnance  Department, 

JKavy.  Department, 

Washington,  D.  C. 

Dear  Admiral : 

Do  you  know  whether  or  not  a  registering  calliper  has 
ever  heen  used  on  the  outside  of  the  gun  when  fired,  to  get  the 
height  of  the  stress  v/ave. 

I  have  been  trying  some  experiments  to  locate  the  pro¬ 
jectile  after  leaving  the  gun,  without  any  loss  of  ponder  pres¬ 
sure.  In  my  experiments  I  use  a  catapult  to  obtain  slow  velocity 
and  thereby  get  maximum  tumbling.  I  thon  tried  the  correct  the 
tumbling  by  revolving  the  projectile.  Che  experiments  are  promis¬ 
ing.  She  rifling  of  a  gun  appears  to  me  very  objectionable. 

Yours  very  truly/.

At  the  meeting  of  Committees  of  the  Haval  Consulting 
Board,  on  the  22na  instant,  nothing  of  very  serious  import 
took  place,  except  of  the  meeting  of  the  Committee  on  Ordnance 
and  Explosives,  of  which  Hudson  Maxim  is  Chairman. 

She  following  are  some  <£  the  notes  I  made,  taken 
from  the  conversation: 

1.  Ur.  Hunt  reported  that  a  man  named  Weeden-fclarshall 
came  to  Hew  York  and  gave  the  license  to  someone  to  manufacture 
his  new  gun.  It  was  a  shoulder  type,  weighs  eight  pounds.  The 
recoil  is  taken  up  hy  some  sort  of  mechanism  that  prevents  the 
gun  from  kicking.  Expects  to  put  one  in  the  hands  of  Mr.  Hunt 
for  test  at  an  early  datd. 

2.  Mr.  Maxim  attributes  erosion  to  heat.  Says  the 
effect  is  like  that  which  would  result  if  shooting  a  projectile 
with  steam  in  an  ice  gun.  The  inside  surface  would  he  melted 
slightly. 


3.  Dr.  Woodward  wanted  to  cover  the  projectile  with 
some  metal  that  will  not  wear  the  rifling,  hut  Maxim  says 
lubrication  does  not  help  any.  It  is  a  matter  of  temperature. 

The  inside  skin  of  the  gun  is  heated  to  great  temperature. 

Says  that  shooting  a  twelve-inch  gun  sufficient 

energy  to  melt  750  pounds  of  cast  iron. 

4.  Dr.  Baekeland  called  attention  to  the  danger  of 

a  country  blockading  the  nitrate  fields  of  Chile,  and  recommended 
a  Government  plant  for  the  making  of  nitrate.  Says  it  is 
impossible  to  contruct  a  nitrating  plant  in  less  than  a  year, 
and  have  it  operative  with  trained  staff.  It  is  a  government 
enterprise,  because  nitrate  of  soda  can  now  be  purchased 
commercially  from  Chile  dheaper  than  it  can  be  made  by  water¬ 
power.  Maxim  though  nitrate  of  ammonia  could  be  made  under 
four  cents  a  pound.  Baekeland  says  that  even  Horway  with  water¬ 
power  at  six  dollars  per  horsepower  year,  has  no  mineral  for 
the  manufacturing  of- nitrate,  but  that  nitrite  (used  in  dyes) 
gotten  as  a  by-product,  turns  the  tide  in  favor  of  a  profit 
to  the  extent  of  five  percent  dividends  on  the  part  of  the 
companies  formed  for  the.  purpose. 

Dr.  Baekeland  says  Germany  is  making  nitrates, 


but  at  great  expense.  But  they  are  independent. 


,  Mr.  Hunt^that  a 
3  might  buy  and  sto 


an  alternative  against  building  a 
3  nitrates  of  soda  in  large  ouantitiei 


6.  Dr.  Baekeland  recommends  the  expenditure  of  one 
rtn-iiar<3  for  a  nitrating  plant  and  to  run  one  unit  of 
the^plant  constantly  to  get  the  personnel  expert  in  the  handling 
of  it.  Also  buy  nitrates  in  addition,  and  store  them. 

7  Mr.  Hunt  says  that  250:  tons  of  nitrate  Per  day, 
for  three  years  (1095  days)  will  total  273,000  tons  whi*  at 
|?0  00  per  ton  present  market  price,  will  make  an  investment 
of  twelve  million  dollars  to  hold  this  quantity  of  nitrates 
in  storage. 

8  Mr.  Hunt  thought  that  the  Committee  ought  to  cornpile 
a  report;  trSJSit  to  the  entire  Board  and  have  the  Board 

in  turn  transmit. it  to  the  Davy  Department  as  a  warning. 

9.  Dr.  Baekeland  says  eyanamide  method  is  better 

and  after  expending  millions  of  dollars  on  it  they 

-  .  -la  n  K  The  cvanamide  method  is  potassium  chloride, 

S1»,V  requires  oh.ap  hors.pe.er, 

10.  Mr.  Sprague  suggested  that  Dr.  Baekeland  and  Mr. 

Hunt  prepare  a  resort  as  to  what  the  plant  will  consist  of. 

11.  Dr.  Baekeland  thinks  that  means  will  have  to:  be 
devised  for  tabling  things  'through  the  Havy  Department  without 
stirring  up  the  Naval  Officials  antagonistically. 

12  Mr.  Sprague  referred  to  delays  of  the  Navy  Dept, 
in  answering  letters  he  had  addressed  to  them. 


M.  3.  HUTCHISON 


December  27,  1915. 


Mr.  Edison: 

At  the  meeting  of  the  Naval  Consol ting  Board, 
on  the  evening  of  the  22nd  instant,  at  the  Engineering  Societies 
Building,  there  were  present,  beside  the  Board,  Hear  Admirals 
Griffin,  Strauss  and  Taylor,  and  Captain  Smith. 

A  general  discussion  was  entered  into  in  reference 
to  gun  erosion. 

Strauss  says  that  someone  invented  a  smooth  bore 
gun  somevears  ago,  with  grooves  cut  spirally  around  the  project¬ 
ile  In  In  effort  to  spin  the  projectile  without  rifling  being 
in  the  gun.  He  says  that  it  was  not  a  success  because  of  the 
escape  of  the  gases  through  these  grooves  ,  with  resulting 
decreased  range  of  the  guns. 


Strauss  says  that  they  have  i 
testing  erosive  qualities  of  metals. 


i  apparatus  for 


As  a  rule,  alloy  steels  erode  worse  than  other 


Plain  carbon  steel  is  the  best. 

No  titanium  alloy  steel  has  been  tried. 

Mr.  Laemme  says  that  copper  is  the  only  material 
that  will  not  blister  by  heat. 

Admiral  Strauss  says  that  the  bore  of  the  14" 
gun  increases  three  one-thousandths  of  an  inch  each  round. 

Mr.  Whitney  is  making  a  small  valve  with  a  very 
thin  skin  of  copper  to  see  if  erosion  will  not  be  cut 
down  when  bullets  are  fired  out  of  this  valve. 

Admiral  Strauss  says  that  the  erosion  at  the  end 
of  the  bore  does  notamount  to  very  much. 

Admiral  Strauss  says  the  initial  pressure  in  the 
combustion  chamber  is  17  tons  per  square  inch  and  the 
pressure  -  when  the  projectile  is  just  about  to  leave  the  gun 
is  five  tons  per  square  inch,  on  a  14"  gun. 

The  rest  of  the  time  was  taken  up  in  general  dis¬ 
cussion  in  the  asking  and  answering  of  foolish  questions  in 
which  Professor  Webster  predominated  a3  to  the  interrogation 
part.  Unfortunately,  Mr.  Saunders  could  not  be  present  during 
the  first  part  of  the  meeting,  but  when  things  got  to  humming 
and  everybody  was  running  around  in  circles,  I  went  out  and 
got  hold  of  Mr.  Saunders,  asking  him  to  come  in  and  preside. 


As  soon  as  he  arrived,  he  put  things  into  shape  ,  and  ve:y  soon 
thereafter,  brought  things  to  a  close.

utes  talk  with  you  about  the  United  States  Navy. 

I  have  recently  been  asked  to  act  as  Chairman 
of  a  sort  of  Naval  Committee  of  the  National  Security 
league  and  to  read  a  paper  before  a  Congress  of  the  League 
to  be  held  in  Washington  on  the  21st,  22nd  and  23rd  of 
January.  During  the  last  fifteen  years  I  have  had  a  good 
deal  to  do  with  the  English,  Herman  and  Japanese  NavieB 
and  Shipbuilders,  which  are  using  five  million  or  more 
horse  power  of  my  steam  turbines,  as  well  as  with  the 
United  PtateB  Navy,  and  1  am  naturally  interested  in  all 
sensible  efforts  to  give  the  United  States  such  a  Navy 
as  it  should  have . 

T  have  talked  with  some  of  the  active  men  of 
the  Navy  League,  some  of  the  Navy  Advisory  Board,  and  a 
good  many  other  men  of  prominence,  and  I  am  struck  with 


the  great  .desirability  of  a  unanimity  of  purpose  among  the 
different  organizations  working  oh  this  matter. 

Valuing  most  highly  your  views  in  regard  to  our 
Navy,  I  should  like  to  have  a  short  talk  with  you,  and  if 
you  can  spare  a  few  minutes  I  will  run  out  to  West  Orange 
in  my  car  at  any  time  that  will  be  most  convenient  to  you.

your  letters  to  each  member  of  the  Board  with  the  request  that  they  express 
their  opinion  as  to  the  desirability  of  the  Hew  York  Eavy  Yard  as  a  place 
for  future  meetings  of  the  Board.  I  myself  am  heartily  in  favor  of  holding 
all  meetings  there  unless  there  happens  to  be  at  some  particular  time  a 
special  reason  for  meeting  in  Washington  or  at  some  other  point. 

After  the  last  meeting,  in  talking  with  Captain  Burd,  I  told  him 
that  if  we  could  only  arrange  the  matter  of  entertainment  so  that  we  could 
provide  our  own  luncheon,  X  felt  sure  that  the  Board  would  rather  meet  in 
the  Havy  Yard  than  anywhere  else.  He  expressed  much  satisfaction  at  this, 
and  as  to  the  luncheon,  he  said  that  he  must  insist  on  our  being  his 
guests  at  the  next  meeting,  and  that  after  that  time  we  could  do  as  we 
liked.  After  we  have  heard  from  our  members,  I  will  see  him  again  and 
try  to  persuade  him  to  give  up  the  idea  of  entertaining  us. 

Hot  being  aware  that  you  were  writing  Admiral  Usher,  I  took  it  upon 
myself  to  say  that  I  had  been  officially  instructed  to  thank  him  for  his 
kindness  and  so  forth,  as  per  copy  of  letter  I  enclose.  X  havejone^the

your  coming,  to  make  sure  that  1  Bhall  he  avail¬ 
able  . 

Yours  very  truly. 


At  the  request  of  the  Secretary  of  the  Wavy, 

I  am  about  to  undertake  to  form  several  companies  oT  llaval 
Reserve  from  among  our  employees. 


The  Secretary  says  that  if  you  will  take  the 
initiative  in  doing  this,  a  great  many  commercial  concerns 
will  follow  suit,  and  it  will  he  of  the  utmost  assistance 
to  the  cause  of  preparedness. 

I  talked  with  you  once  before  on  this,  when 
we  were  at  Washington  on  the  Naval  Consulting  Board,  and 
you  ;fcold  me  to  go  ahead. 


I  understood  you  to  say,  at  the  time,  that 
anvmen  who  would  go  into  the  Naval  Reserve,  you  would 
give  the  necessary  two  weeks  leave  of  absence  each  Summer 
to  enable  them  to  go  on  the  practice  cruise  called  for  by 
the  regulations  ./  wY  n  rteui*  u/kih 

In  getting  up  these  companies,  I  will;  of 
course,  consult  with  Messrs.  Wilson,  Bachman,  John  Miller 
and  Mallory,  so  as  not  to  have  enough  men  absent  from  any 
one  department  to  interfere  with  the  operation  of  that 
department. 


If  the  matter  is  handled  as  I  enpect  to 
handle  it.  the  resulting  advertising  will  be  of  considerable 
value  in  addition  to  the  result  that  is  bound  to  accrue 
through  the  military  training  of  several  hundred  men 
in  our  organization. 


Before  going  ahead  actively  in  the  matter, 
I  want  to  put  the  matter  again  before  you.

X  noticed  in  the  Times  reference  to  a  stie  which 
you  had  under  consideration  on  the  Newark  Bay.  Possibly 
you  are  not  familiar  with  the  conditions  prevailing  in  this 
Newark  Bay  through  the  v/inter  months.  There  is  a  large 
area  of  this  Bay  in  which  the  water  is  very  shallow  and 
it  is  all  frozen  over,  sometimes  for  a  matter  of  three  or 
four  months.  On  account  of  the  New  Jersey  Central  bridge 
at  the  lower  end  of  the  Bay,  the  ice  backs  in  and  covers 
not  only  the  flats  of  the  Bay,  but  also  seriously  affects 


#2.  T.  A.  E. 

the  channel.  I  believe  the  depth  of  water  in  thiB  channel 
is  not  over  20  feet.  By  way  of  comparison,  I  might  state 
that  the  Staten  Island  Sound,  which  includes  Arthur  Kill 
and  Kill  von  Kull,  during  my  experience  as  owner  for 
fifteen  years,  has  never  been  frozen  over  and  traffic  has 
never  been  interfered  with  by  ice.  The  large  propellers 
and  freighters  which  pass  through  this  waterway  keep  it 
from  being  closed.  As  you  know,  sane  33,000,000  tons 
passed  through  thiB  waterway  last  year.  Our  depth  of 
water  at  low  tide  is  25  feet,  and  vessels  27  to  28  feet 
draught  can  dock  at  our  property. 

I  am  enclosing  you  another  set  of  Maps  so  that 
if  you  have  parted  with  yours  you  will  have  a  new  set.  for 
reference. 


Very  truly  yours.

December  30th.,  1915. 


My  dear  Hr.  Edison: - 

Thanks  for  your jrourteous 
letter  of  the  37th,  the  sentiments  oi/which  X 
greatly  appreciate. 

It  did  not  oc$sur  to  me  that 
X  could  not  carry  along  at  the  same  time  my  work 
for  the  national  defense  movement  and  tne  technical 
work  which  I  had  wished  to  do  upon  the  Board, until 
Mr.  Saunders  told  me  several  weeks  ago  that  my 
criticisms  of  the  Administration's  recommendations 
had  disturbed  some  of  my  associates, who  felt  them 
to  he  inimical  to  the  best  interests  of  the  Board. 

I  needed  no  further  intimation  than  this  to  make 
it  clear  to  me  where  my  duty  lay,  and  thereupon 
made  up  my  mind  to  resign  from  the  Board  so  soon 
as  I  should  become  convinced  that  the  Administration 
was  determined  not  to  enlarge  its  program,  so  that 
my  activities  should  not  jeopardize  the  success  of 
the  tremendous  undertaking  which  you  have  put  on 
foot. 

How  bitterly  it  has  hurt  me 
to  surrender  the  long  wished  for  opportunity  to 
collaborate  with  you  as  a  devoted  disciple  only  the 
immediate  members  of  my  family  are  aware. 


Cordially, 


Committee  on  Chemistry  afnd  Physios, 

U.S.  Havel  Consulting  hoard 

Dear  Sir: 

•  I  hove  reooived  copy  of  Professor  Richards’ 
suggestion  on  phosphide  homhs  for  submarine  signals. 

ThiB  raises  a  praotioel  question  on  whioh  I  hod  planned 
to  write  you  todey. 

I  am  trying  to  help  Mr.  Edison  hy  getting  out 
at  short  notioe  blueprints  of  the  floors  of  the  Physios 
and  Chemistry  laboratory.  In  oonneotion  with  this  I 

had  thought  that,  the  problems  whioh  oome  under  the  head 
of  PhysioB  and  Chemistry  and  whioh  should  be  undertaken 
in  that  laboratory,  oould  well  bo  attaohed  to  the  plans 
themselves.  1’or  example,  referring  to  Hoom  10.  In 
thiB  room  is  supposed  to  he  undertaken  suoh  physiool  work 
as  rofers  to  wireless  signalling,  amplifiers,  oto.  This 
might  include  oil  suoh  apparatus  as  required  vaouum  ap¬ 
paratus.  Another  room,  say  Ho.  11,  is  devoted  to  the 
use  of  liquid  air,  oomprosBed  oxygon,  eto.,  in  oonneotion 
with  fuels  or  power  for  torpedoes. 


Of  course  there  is  no  intention  of  confining 
any  particular  room  entirely  to  a  single  problem,  but  I 
thought  it  might  be  well  to  show  that  there  are  very 
definite  ana  important  problomo  for  which  roomB  could 
be  prepared.  It  in  in  this  connection  that  I  should 
like  tory  much  to  oolleot  the  suggestions  of  members  of 
the  Committee,  so  that  the  choice  of  specific  investigations 
would  be  a  good  one.  If  each  member  will  prepare  such 
a  list  as  soon  as  possible  I  will  incorporate  it  into 
the  preliminary  plana,  which  I  assume  must  go  to  Mr. 

Edison  within  a  very  few  days.  I  will  attempt  to 
incorporate  also  any  suggestion  you  may  make  in  connection 
with  the  construction  of  the  laboratory  or  the  details 
of  the  equipment. 

A  few  of  tho  problems  which  would  naturally 
bo  attacked  in  thin  laboratory  are  the  following,  most 
of  which  are  from  the  list  given  us  hy  the  Havy  Department: 

1.  increasing  the  "life"  of  the  gyroscope 
for  tho  torpedo. 

It  is  possible  that  in  a  highly 
ovaouatod  spaoo  the  gyroscope  oould 
he  oonstruoted  and  operated  without 
meohanionl  connection  to  the  ^Bgered 
anorp-7  used  in  operating  the  valves, 
but  conns o tod  in  somo  other  non-consuming 


2,  Hydrogen  from  storage  batteries, 
itB  detootion  and  removal. 


3.  Detecting  submarines  at  a  distanoe. 


Cortain  experiments  on  sound  oo Damns 
in  water  seem  to  ub  of  inter BRt  here. 

4.  light ,  non-inflammable  deck  oovering. 

Do  you  agree  that  something  like  a 
magnesium  oxide,  magnesium  chloride 
asbestos  mixturoa  might  repay  in¬ 
vestigation? 

5.  Oil  oooling  for  small  Diesel  engines. 


Shis  is  a  physical  or  thermal  con¬ 
duction  problem,  but  I  think  it  would 
soon  bo  found  that  the  phaotioal  prob¬ 
lem  involves  the  polymerizing  of  the  oil 
on  tho  hot  surfaoe  and  the  more  or  less 
rapid  diminution  of  tho  ability  of  the 
oil  to  remove  the  heat  from  the  hot  sur¬ 
face.  Simple  laboratory  experiments 
would  show  whether  this  is  oorreot  or  not. 


6.  Alloys  for  speoiflo  purposes,  suoh  as 
non-oorroding  exterior  portion  of  gun 
mechanisms  for  the  externally  mounted 
submarine  gum.  I  believe  that  the 
study  of  the  aluminum-0 opper  alloys  is 
important  in  this  oonneotion. 

7.  Condenser  and  boiler  tube  material. 


Various  alloys  should  be  tried  for 
these  uses.  It  seems  now  as  tho 
Calorized  copper  is  a  promising  material. 


8.  Exploaivo  mixtures. 


In  oonnootion  with  Professor  RiohardB' 
suggestion,  would  it  moot  with  you r  approval  to  refer 
thiB  to  the  Havy  Department  an  a  problem  suitable  for 
investigation  in  the  proposed  laboratory,  or  would 
you  prefer  that  suggestion  be  made  that  it  be  investi¬ 
gated  at  onoe,  and  if  bo,  by  whom?  It  seems  as  <ho 
thore  might  be  problems  such  as  thin  where  a  definite 
Buggoetion  by  ue  that  it  bo  investigated  at  onoe  by 
some  laboratory  (for  example,  a  oollege  laboratory), 
might  be  a  proper  disposition. 

YourB  very  truly,

Dear  Sir:-  |Wm>  «Um  ™-w  £Urt- 

In  the  hope  of  enlisting  your  fn t^est^juponj^  ^abject 

which  I  have  had  at  heart  forsome  time, ^namely  that  of  gfvipg- the 
unfortunate  crew  in  a  sunken  sub-marine,  a  chance  to  escapS  dilve , 
and  reach  a  point  of  safety,  I  take  the  liberty  to  submit  specifica¬ 
tions  and  crude  drawings  for  a  life  boat,  which  is  intended  to  be 
attached  or  rather  sunken  in  a  cradle  upon  the  deck  of  submarines. 

You  will  note  I  have  submitted  these  plans  to  Secretary 
Daniels,  and  also  the  result.  However  I  feel  sure  the  idea  is  a  prac¬ 
tical  one  and  so  far  as .1  am  able  to  learn,  much  superior  to  anything 
they  now  have. 


I  believe  if  you  took  the  matter  in  hand,  the  sketches 
redrawn  more  clearly,  possibly  a  model  made,  experiments  etc.,  more 
consideration  and  importance  would  be  attached  and  possibly  so  much 
stress  would  not  be  laid  on  "a  sacrifice  of  military  features",  but 
rather  adopted  for  the  sake  of  humanity. 


In  the  hope  my  poor  efforts  may  be  of  interest  to  you, 
I  beg  to  remain. 


Very  respectfully.

which  is  the  largest  organization  working  for  de-  p 
fense,  is  to  hold  a  National  Security  Congress  i 

Washington  on  January  20th,  21st,  and  22nd,  at  WA  , 

which  it  is  purposed  to  have  read  papers  on  ap-  *  i  /

in  this  country  -  Mr.  Roosevelts  among  thorn.  The 
enclosed  announcement  will  give  you  further  info u» i vk 

As  this  Congress  will  be  of^® 
great  national  importance,  and  cannot  fail  to  ef-rt 
feet  favorable  protective  legislation,  which  is  sd"  :/ 
urgently  needed,  I  am  going  to  beg  you  to  prepare 
for  it  a  paper  dealing  with  the  Naval  Consulting  / 

Board  and  its  laboratory  project.  If  this  subject/ 
is  not  dealt  with  at  all  it  is  apt  to  be  considered 
as  of  minor  importance,  whereas  if  a  paper  written 
■by  you  can  “be  read,  setting  forth  the  “benefits  to 
“be  derived  from  this  most  necessary  institution,  its 
value  will  be  reimpressed  upon  the  country  and  upon 
Congress, and  the  legislation  which  you  most  ..earnest¬ 
ly  desire  will  the  more  easily  be  got. 

Although,  unfortunately,  I  am 
no  longer  a  member  of  the  Board, I  have  its  interests 
at  heart,  and  shall  use  every  available  means  to 
assist  you  to  carry  out  your  undertaking.

My  dear  Mr .  V.ood : 

I  have  received  your  favor  of  the  fifth  instant 
in  regard  to  the  propoBod  meeting  of  the  national  Soourity  Con- 
gross,  and  have  noted  its  contents  as  also  those  of  the  papers 
accompanying  your  letter. 

I  am  no  hand  at  preparing  papers,  as  that  sort 
of  thing  is  entirely  outside  of  my  lines.  X  am  going  to  stiok 
close  to  actual  work,  and  have  nearly  completed  blue  prints  of 
the  plane,  details  and  machinery  and  everything  for  the  pro¬ 
posed  Government  Laboratory.  These  should  be  finished  next 
week,  together  with  a  report  of  the  approximate  cost.  In  addi¬ 
tion,  I  have  sevoral  men  experimenting  at  the  present  on  the 
erosion  of  guns,  which  to  my  mind  is  a  very  important  subject,  as 
erosion  limits  the  size  and  fang  of  big  guns. 

I  would  greatly  prefer  not  to  say  anything  about 
the  Ilaval  Consulting  Board,  but  am  willing,  however,  to  appear 
before  the  Congressional  Ilaval  Board  if  so  deBired  and  stand 
cross  examination. 


Yours  very  truly,

After  a  groat  deal  of  general  discussion,  it  was  deoidod  to  ask 
the  urosidont  of  tho  United  Staton  through  the  Sooretary  of  the  I^vy.  to.  ^

manufacturing  lndustrios  of  tho  country  to  serve  tho  Government. 


While  wo  all  agreed  that  cany  other  Sociotion  might  render 
valuable  service,  yet  it  was  thought  dosirahle  to  rentriot  the 
membership  to  a  smaller  rather  than  a  larger  number,  as  being  more  conducive 
to  effective  work,  and  furthermore,  it  was  felt  that  the  more  specialised 
Societies  wore  represented  in  tho  membership  of  those  mentioned.

iir.  -Edison: 

I  find  tho  Committee  on  Aeronautics  of  the  Haval 
Consulting  Board  did  invite  representatives  of  practically 
all  the  large  aeroplane  companies  of  the  United  States  to 
attend  a  meeting  held  at  the  Engineering  Societies  Bldg, 

Hew  York  City,  last  week. 

nothing  was  said  to  you,  as  Chairman  of  the  Board, 
that  such  a  meeting  was  to  he  held. 

It  seens  to  me  as  Chairman  of  the  Board,  you  should 
know  that  such  an  important  meeting  is  to  he  held,  heoause  I 
could  go  in  and  see  what's  gointr  on,  and  keep  you  posted. 

I  suggest  it  would  he  a  good  scheme  to  write  a 
letter  to  Robins,  politely  suggesting  that  you  he  notified 
when  any  such  important  meeting  as  that  is  to  he  held  in  future. 

I  understand  the  ^eronatical  Society  is  very  much 
upset  heoause  they  were  not  invited  1,0’  attend  the  conference, 
whereas  the  Society  of  Aeronautical  Engineers  did  participate. 

If  that  hunch  in  the  Board  gets  hailing  things  up  so  that 
engineering  societies  will  he  fussing  am  ong  themselves,  with 
the  personal  eouation  so  strong  as  it  is  on  the  subject  of 
being  against  the  Aeronautical  Society,  it  will  cause  friction 
in  the  Board. 

You,  as  Chairman,  should  he  apprised  of  any 
mooting  in  which  outside  people  are  to  he  called,  and  such  meeting 
as  that  should  have  your  sanction  before  it  can  he  held.

My  dear  Mr.  Edison: 

I  have  been  a  Tt_, _ w  _  _  . 

letter  of  December  27th,  and  X  apologize  for  my  i 
gleet.  I  made  some  inquiries  on  Receiving  it,  to 
asoertain  whether  or  not  any  one  else  had  made  the 
measurements  you  inquired  about,  end  as  far  as  I  can 
learn  they  have  not:  we  never  made  them. 


In  a  well  constructed  gun  the  actual  expansion 
of  the  outside  diameter  when  the  powder  pressure  is 
on  can  be  readily  calculated,  and  if  you  wish  I  can 
procure  them  for  you,  and  I  believe  they  will  be 
correct  within  practical  limits. 


I  am  deeply  interested  in  the  fact  that  you  have 
gone  into  the  matter  of  rifling  and  erosion,  and 
hope  that  with  your  energy  and  the  facilities  that 
you  enjoy,  much  good  will  come  of  it. 

X  hope  to  arrange  with  Hutchison  some  day  very 
soon  a  visit  to  you  so  that  we  may  talk  over  the 
whole  matter  with  as  much  time  as  you  care  to  give

W.  A.  Meadowcroft,  Esq., 

" — The  Thomas  A.  Edison  Laboratory, 

?)0  \  Orange,  II.  J. 

Dear  Sir: 

y  V/IRE  DESTROYING  PROJECTILE. 

My  anxiety  to  have  my  invention  tested  by  field 
experiments,  and  to  get  it  into  actual  life-saving  service  on 
the  battle  fronts  of  Europe  must  be  my  apology  for  again  dis- 
traoting  the  attention  of  so  busy  a  man  as  your  good  self. 
Tumbling  in  Plight:  You  remember  Mr.  Edison  specified  this 
as  the  condemning  feature  of  projectiles  with  extending  flukes 
or  blades.  That  is  true  of  projectiles  having  their  flukes 
hinged,  or  otherwise  attached,  in  the  forward  part  of  the 
body,  and  those  which  open  upon  emerging  from  the  gun.  In  my 
device  the  blades  are  pivoted  in  the  rear  part  of  the  projec¬ 
tile  and  are  securely  locked  in  their  closed  position  in  corres¬ 
ponding  channels.  In  this  condition  the  projectile,  fired  from 
a  service  rifled  gun,  has  as  great  a  range  and  aB  true  a  flight 
as  any  projectile  of  similar  caliber. 

The  simple  mechanism  for  releasing  the  blades  can  be 
timed  to  accuracy  equal  to  that  of  shrapnel  or  other  shells,  to 
act,  say  50  or  even  100  yards  short  of  the  object  of  attack. 

The  weight  of  metal  in  the  forward  part  of  the  body  of  the  pro¬ 
jectile,  and  the  atmospheric  resistance  acting  againBt  the  open 


■blades ,  operate  exactly  as  in  the  case  of  the  small  boy's 
feathered  dart.  It  cannot  change  its  head-on  flight. 

You  will  note  that  the  blades  open  to  an  angle  raking 
aft  about  12°  from  a  right  angle  with  the  axial  line  of  the 
body,  which  heightens  its  similarity  to  a  dart  in  flight. 

Let  me  repeat  that  my  tests  of  the  device,  in  miniature 
proved  the  correctness  of  the  foregoing. 

Because  it  is  so  urgently  needed  I  am  most  anxious 
that  the  proper  expert  artillery  officials  make  the  tests  which, 
for  obvious  reasons,  I  myself  am  unable  to  make. 

Forgive  my  persistence  and  prolixity  and  believe  me. 


Faithfully  yours,

that  he  thinks  your  scheme  will  probably  go 
through  the  Haval  Consulting  Board  too  slowly 
to  suit  you.  His  idea  is  that  perhaps  you 
had  better  take  it  up  direct  with  the  military 
and  get  a  quick  test.

In  the  original  resolution  passed  lpy  the  Board,  some 


to  the  most  dgsirable  location,

specifications  were  made 
and  it  occurred  to  me  that  the  site  of; 

Bronx  Terminal  Corporation  (concerning  which  this  company 
is  writing  you)  complied  with  practically  all  of  the 
requirements  originally  set  forth.  Upon  finding  that 
the  owners  were  open  to  some  sort  of  an  arrangement  for 


the  use  of  their  property,  I  asked  them  to  furnish  me 
with  details,  which  I  forwarded  to  Mr.  Whitney,  who 
in  turn  suggested  that  duplicate  copies  be  sent  to  you 
and  to  Mr.  Edison.  This  has  been  done,  as  I  am  informed 
by  letter  received  from  the  company  this  morning. 

In  their  letter  they  state  that  they  would  be  very 
glad  to  have  you  and  the  Board,  or  any  of  its  members, 
examine  the  property  at  any  time,  and  would  be  pleased 
to  provide  automobiles  to  drive  to  and  over  the  property

To  the  members  of  the: 

American  Society  of  Civil  Engineers, 

American  Institute  of  Mining  Engineers, 

American  Society  of  Mechanical  Engineers, 

American  Institute  of  Electrical  Engineers, 

American  Institute  of  Consulting  Engineers, 

Gentlemen: - 

There  has  been  introduced  into  the  Senate  a  Bill 
(S-3946)  providing  for  the  extension  of  the  military  training 
now  given  in  land-grant  colleges  and  other-  civil  educational  in¬ 
stitutions  in  which  military  training  is  given,  and  for  the  es¬ 
tablishment  of  military  instruction  in  such  other  institutions 
as  elect  to  come  under  the  provisions  of  the  Bill,  The  prime 
objeot  of  the  Bill  is  that  of  building  up  a  reserve  of  trained 
officers  available  for  officering  volunteer  foroes  in  case  of 
war.  In  the  opinion  of  the  undersigned  the  plan  of  the  Bill  will 
accomplish  this,  and  at  minimum  cost  to  the  nation;  and  will, 
at  the  same  time,  provide  an  element  of  discipline  and  training 
of  great  value  in  the  civil  life  both  of  the  individuals  under¬ 
going  it  and  of  the  community. 

Enclosed  herewith  is  a  brief  statement  of  the  prin¬ 
cipal  points  covered  by  the  Bill,  together  with  an  answered 
questionnaire  covering  such  points  of  information  as  would  be 
desired  by  one  giving  the  Bill  careful  consideration. 

The  plan  contenqplated  by  the  Bill  does  not  in  any  way 
confliot  with  any  of  the  other  plans  proposed  in  the  interest 
of  preparedness.  On  the  contrary,  it  will  supplement  and  fit  in 


[ATTACHMENT/ENCLOSURE] 


with  any  other  plan  which  may  be  adopted,  Whether  it  involve 
training  camps,  a  reserve  officers  training  corps,  a  reserve  of¬ 
ficers  corps,  etc,  or  any  or  all  of  these. 

The  undersigned  earnestly  request  that  the  members  of 
the  various  national  engineering  societies  Bend  personal  letters 
or  telegrams  to  their  individual  Senators  and  Representatives  in 
Congress  asking  them  to  support  Senate  Bills  S  3946.  In  making 
this  request  we  are  acting  as  individuals  and  not  as  the  official 
representatives  of  the  societies.  Each  of  us  1b,  hov/ever,  a  mem¬ 
ber  of  one  or  more  of  the  societies  addressed,  and  we  urge  prompt 
action  of  our  fellow  members  in  the  societies  to  which  we  respect¬ 
ively  belong. 

It  is  your  individual  action  which  we  particularly 
ask  in  this  matter.  In  addition  to  your  individual  letters  and 
telegrams  to  your  Senators  and  Representatives,  it  is  desirable 
that  you  influence  as  many  other  persons  sb  possible  to  take 
similar  action. 

Time  iB  the  essence  of  this  matter.  We  earnestly  re¬ 
quest  that  you  aot  promptly.

Mr.  Pomeeese  introduced  the  following  bill ;  which  was  read  twice  and  referred, 
to  the  Committee  on  Military  Affairs. 


A  BILL 

To  establish  a  Reserve  Ofliccrs  Training  Corps. 

.  l  Be  it  enacted  by  the  Senate  and  House  of  Bepresenta- 

2  tives  of  the  United  States  of  America  in  Congress  assembled, 
8  That  for  the  purpose  of  securing  a  sufficient  reserve  of  officers 
4-  for  the  military  forces  of  the  United  States  the  President  is 

5  hereby  authorized  to  establish  and  maintain  in  civil  educa- 

6  tional  institutions  a  Reserve  Officers  Training  Corps,  which 

7  shall  consist  of  a  senior  division  organized  at  universities  and 

8  colleges  requiring  four  years  of  collegiate  study  for  a  degree, 

9  including  those  State  institutions  that  are  required  to  pro- 

10  vide-  instruction  in  military  tactics  under  the  provisions  of 

11  the  Act  of  Congross.  of  July  second,  eighteen  hundred  and 

12  sixty-two,  donating  lands. for  the  establishment  of  colleges 


X  beg  leave  to  submit  the  following  for  your  con¬ 
sideration:

U>tUv 

therefore  needing  no  protection  other,  than  such  as  aubmdrBion 
gave.  The  result  was  she  was  a  very  small  target.  For 
smooth  water  a  vessel  of  the  Monitorptype^lEr p^oubtedly^ 
a  better  fighting  machine  than  is  a  pociarn  Dreadnought .Jin 
rough  waters,  however,  her  guns  are  too  low  to  be  sd'rviceable, 
but  her  submersion  is  still  asfeood  protection  as  anj^  What 
the  national  defence,  demands,  in  its  Navy,  is  fighting  machines ; 
not  floating  palaces ;  and  why  may  not  such  rough  water  fight¬ 
ing  machines  be  made  to  afford  as  small  a  target  as  did  the 
Monitor  if,  instead  of  building  up  heavily  armored  walls  above 
the  water  line, the  hull  proper  Snd  at  or  near  the  water  line  and 
the  gun  turrets  and  the  observation  masts  only  be  carried  up 
to  the  desired  height.  From  the  observation  mast  she  could 
be  commanded  and  navigated,  when  in  action.  This  would 
reduce  the  size  of  the  target  from  say  500'  X  SO'  to,  say, 


targets  20' X  30' placed,  say,  250'  apart.  Of  course  such 
a  vessel  would  not  be  as  comfortable  for  her  officers  and 
crew  as  is  the  present  standard  vessel,  but  it  v/ould  be 
much  more  comfortable  than  is  a  submarine.  And  as  efficiency 
of  fighting  machine-  not  Ate  userB  comfort,  is  the  first 
consideration,  why  should  not  all  new  vessels  be  built  with 
the  efficiency  end  only  in  view.  For  ordinary  cruising, 
dress  parade,  purposes  there  is  now  an  ample  supply.  Judged 
by  the  present  war,  it  is  speed  and  range  of  guns,  not  armor 
platlpg,  that  has  determined  results;  and  a  vessel  of  the 
type  suggested  could  carry  as  heavy  guns  as  the  present 
type,  and,  being  so  much  lighter,  should  be  susceptible  of 
much  higher  speed.  Given  sufficient  speed,  and  range  of 
guns,  and  one  or  two  vessels  of  the  suggested  type  could, 
at  their  leisure,  annihilate  a  fleet  of  Dreadnoughts . 

Again  the  time  of  construction,  and  particularly  the  cost 
of  construction,  would  be  very  much  less.  The  guns  might 
even  be  mounted  upon  a  Bkeleton  frame  work  only,  through 
which  crew  and  ammunition  should  reach  the  guns,  and  the 
guns  be  given  no  armor  protection  whatever.  This  would 
reduce  the  size  of  the  vulnerable  target  to  the  size  of 
the  guns  themselves,  which,  when  trained  on  the  enemy, 
would  be  practically  a  pin  point.  Or  the  gun  crew 
only  might  be  given  armored  protection. 

Is  it  not  much  better  to  so  provide  that  shots 
shall  pass  harmlessly  by  or  over,  than  it  is  to  build  an 
iron  wall  with  a  view  to  stopping  them?

Replying  to  your  favor  of  the  lbth.  Inst., 
rin  the  matter  of.  the  Government'  Equipment'  laboratory  Site,  there  are  a  numbe'r' 
of  parties  interested  'in  this  Site,  that  would  have  to  be  consulted  t’o  fix  up‘- 
on  the  price.  The  tract  of  land  in  question  is  part'  of  an  eState  and  contains 
upwards  of  200  Acres,  the  greater  part  of  which  is  situated  East  of  and  along 
the  West  Shore  Railroad  and  between  the  said  Railroad  and  'the  tile  water  of  the 
Hudson  River  and  in  a  protected  bason  or  harbor.  Such  a  location  on  the  Hud¬ 
son  River,  you  must  realize,,  is  very  valuable.  There  is  a  portion  of  this 
particular  tract  located  along  said  Railroad  to  the  west  of  same  and  connected 
to  the  portion  to  the  East  thereof  by  an  under  grade  crossing. 

Of  cqrse  the  first,  ’thing  the  parties,  interested  in  this  property 
would  want  to  know  before  they  could,  or  would  fix  upon  a  price  would  be  just 
how  much  of  it,  and  just  what  part  of  it  you  wanted.  If  the  site  should  be  just 
what  you  wanted,  it  might  not  be  advisable,  to  start,  them  thinking  about  the  sel¬ 
ling  or  fixing  upon  the  price  until  you  were  ready,  to  buy  and  dose  the  deal  at 
once.  When  there  is  an  opportunity  given  to.  thlk  the  selling  and  the  price  OVe'r 
with  outsiders  friendly  and  unfriendly,  there  is  no  foreseeing  the  result.  This 
is  a  great  place  for  medlers  of  such  kind,  and  so  the  least  publicity  the  better 

in  this  case.  • , 

If.  it  could  be  conveniently  arranged  and  as  inconspicuously  as  possi¬ 
ble,  I  would  be  pleased  at  any.  time  to  show  the  property  to  you  or  any  menbeV  of 
your  board,  to  ascertain  whether  the  site  is  at  all  suitable  or  not)  and  if  siSthble 
.  to  determine  just  what  part  and  how  much  of  same  would  be  desired.  This  would 
then  offe’r'  a  basis  upon  which  to  fix  the  pric'd.

My  aear  air:-  ,,  V \^V'  ,V  *> 

It  has  been  suggested  that  the  opinion  of  the  members  of 
Naval  Consulting  Board  be  obtained  on  the  following  points: 


Through  the  courtesy  of  the  United  Engineering  Society 
a  suite  of  offices  has  been  placed  at  the  disposal  of  the  Naval  Consulting 
Board,  these  offices  being  now  oocupied  by  the  Committee  on  Production, 
Organization,  Manufacture  and  Standardization.  Adjoining  this  suite  is  a 
large  board  room,  with  table  and  chairs,  sufficient  to  afford  a  place  for 
a  meeting  of  the  Naval  Board.  In  the  Engineering  Societies  Building 
are  stenographers,  clerks,  telephones, eto . ,  all  of  which  are  available 
for  the  use  of  the  Naval  Board  and  which  can  be  obtained,  to  a  reasonable 
extent,  without  charge. 


Immediately  connected  with  the  Engineering  Building 
is  the  Engineers'  Club,  where  luncheon  oan  be  served  for  about  one-third, 
05,  at  a  maximum,  one-half  what  it  costs  to  serve  luncheon  at  the  Brooklyn 
Navy  Yard,  and  in  view  of  the  Inaccessibility  of  the  Brooklyn  Navy  Yard 
it  is  thought  that  the  next  meeting  of  the  Naval  Board  (March  g.)  be  held 
in  the  Naval  Consulting  Board  rooms  in  the  Engineering  Societies  Building 
instead  of  in  the  Brooklyn  Navy  Yard. 


Several  members  of  the  Naval  Board  have  oritioised  the 
faot  that  a  stenographer  is  present  at  the  meetings  of  the  Board.  This, 
of  course,  is  quite  unusual  in  board  meetings.  Freedom  of  disoussion  is 
desirable,  and  there  would  seem  no  particular  reason  for  stenographic  notes, 
but  only  the  usual  memoranda  of  resolutions  passed,  or  things  done  at  the 
Board  meeting,  such  as  is  common  practice  in  business  board  meetings. 

Will  you  be  good  enough  to  let  me  have  your  views  on  these 
two  points  at  your  earliest  convenience? 


1. As  to  holding  the  meeting  on  the  gth  in  the  Engineering 
Sooietles  Building,  29  W«39th  St. 

2.  Whether  you  prefer  that  no  one  but  members  of  the 
Board  be  present  at  the  meetings,  exoept  invited  guests  and  a  stenographer 
on  speoiaj.  oooasions  only. 

The  two  points  are  in  line  with  the  saving  of  expense, 
which  should  be  kept  before  us,  as  some  of  the  activities  of  the  Board 
which  are  contemplated  are  likely  to  run  into  a  good  deal  of  money. 

I  personally  have  spoken  to  the  Secretary  of  the  Navy  about  this  and  am  at 
work  upon  a  plan,  which  I  think  will  be  oarried  out,  to  seoure  a  fund  for 
aotual  expenses  only.

Mr.  V, .  L.  Saunders,  Second  Vice  President, 

Ueval  Consulting  Board  of  the  United  States, 

11  Broadway,

Dear  Mr.  Saunders: 

I  have  been  so  exceedingly  busy  working  days 
and  nights  this  week  that  I  have  only  seen  your  favor  of  the 
first  instant  this  morning. 

I  think  it  would  bo  preferable  to  hold  the 
meetings  of  the  Board  at  the  Havy  Yard,  ft  connects  us  more 
directly  with  the  Government  than  if  we  met  in  some  build¬ 
ing  in  Hew  York  City.  As  to  expense,  1  do  not  see  that  it 
will  mako  much  difference  to  the  Board  whether  they  eat  at 
tho  Waldorf  or  the  Havy  Yard  or  elsewhere. 

On  the  whole  it  is  my  opinion  that  it  will  be 
better  to  have  a  stenographer  take  notes  at  a  signal  from  the 
Presiding  Office. 

Yours  very  truly.

that  is,  the  meeting  on  Wednesday,  the  Sth  of  March.  We  held  a  meeting 
at  the  Brooklyn  Navy  Yard  only  a  month  ago,  and  the  weather  is  very  bad 
Just  now.  Furthermore  we  have  a  suite  of  offices  Just  given  us  for  nothing 
at  the  Engineering  Societies  Building  and  it  is  thought  advisable  to  get 
acquainted  with  them.  Mr.  Robins  will  send  out  notice  that  the  meeting 
on  the  Sth  will  be  held  at  the  Engineering  Societies  Building.  We  can

Thomas  A.  Edison,  Esq., 

Orange,  N.  J. 
hear  Mr.  Edison; 

My  old  friend  and  former  client,  Captain  Alexander 
Mchougall,  of  Duluth ,  Minn.,  has  asked  me  to  write  you  arid 
urge  upon  you  to  see  him  in  reference  to  a  Coast  Defense  plan 
which  he  has  developed  and  which  he  wishes  to  bring  to  the  atten¬ 
tion  of  the  Naval  Consulting  Board.  I  do  not  know  anything  about 
the  merits  of  the  plan,  but  I  can  say  for  Captain  McDougall  that 
he  is  a  thoroughly  practical  man  in  every  sense  of  the  word,  and 
any  plan  that  he  might  propose  I  .should  say  would  certainly 
be  worth  looking  into. 


Captain  MoDougall  invented  the  whale;-back  type  of 
boat  and  has  had  a  great  deal  of  practical  shipbuilding  experience, 
having  built  more  than  one  hundred  steel  vessels.  The  Christopher 
Columbus  built  by  him  in  1893  is  still  in  commission  between 
Chicago  aid  Milwaukee. 

I  understand  that  he  has  been  working  for  three  or  four 
years  on  his  Coast  Defense  plan  and  has  models  and  drawings  which 
fully  illustrate  the  same.  I  think  by  all  means  you  should  see 
him,  and  X  can  commend  him  in  every  way  as  an  honest,  hard  headed 
thoroughly  practical  Scotch  Canadian. 

With  best  wishes, 


Yours  very  truly,

Your  favor  of  the  sixth  inBtant  -.o  Mr.  Edison  was 
received  and  laid  before  him.  Ue  has  been  on  one  of  his 
characteristic  experimenting  campaigns  daring  the  last  five 
or  six  weoks,  and  is  very  busy,  to  he  has  askod  me  to  reply. 

He  asys  that  your  friena  Captain  McDougall  may 
write  out  his  scheme  and  send  it  on  here,  and  .Mr.  Edison 
will  forward  it  to  the  Secretary  of  the  Havel  Consulting 
3  ard.  When  we  are  writing  inquirers  on  this  subject  we 
suggest  that  they  should  protect  themselves  either  by  fil¬ 
ing  an  application  for  patent  or  keeping  the  original  of 
the  description,  dated  and  v/itnessod.  Mr.  Edison. cannot 
guarantee  any  privacy  in  the  matter  after  it  leaves  his 
hands . 

With  kind  regards,  I  remain.

New  York  City. 

The  Sun  is  publishing  statements  about  the  submariner  battery 
without  investigating  and  ascertaining  the  facts.  Nothing  in 
the  Battery  Company's  pamphlet  explains  anything  but  what  haB 
been  known  for  several  years-  The  Naval  authorities  contri¬ 
buted  nothing  to  advance  the  battery.  It  s  coBt  has  been  very 
much  more  than  I  received  from  the  Government.

the  business  of  the  meetings. 

4  Dr.  Whitney  read  a  memorandum  addressed  to  the  Committees  on 
Chemistry"  Physics ,  Ordnance  and  Explosives  previously,  in  regard 
to  getting  some  action  immediately  on  of  nitrogen 

of  the  air.  Discussion  and  general  approval  of  some  plan. 

6  A  Mr.  Bower,  representative  of  the  Farmers’  Union and  the 

25SS  2M.S2JA 

farmers  in  peace  time  and  by  the  Government  in  war  time.  Says  the 
farmers  are  behind  such  a  movement. 

£0eLL°\£rt^ 


Does  not  ask  that  the  plant  he  located  in  any  one  particular 
locality,  only  that  it  he  placed  with  due  respect  of  source  of 
supply  of  raw  material,  and  for  the  demand/.  Cannot  see  any  reason 
for  raising  a  political,  question  as  to  locality,  hut  wants  results. 
Thinks  that  several  plants  should  he  installed  and  located  in 
various  parts  of  the  Country  to  correspond  with  the  demand  and 
souroe  of  supply  of  raw  material,  etc. 

Farmers  now  use  175,000,000  dollars  worth  of  fertilizer  per  annum. 
Thinks  that  nitrogen  and  nitrates  are  most  important. 

Can  use  phosphoric  acid  and  potash  at  present  market  prices  and 
get  economic  returns. 

Thinks  such  a  plant  is  of  more  importance  to  agriculture  thai  to 
the  Government,  provided  the  Government  can  he  served  during  war 
time.  From  90?£  to  95fr  of  the  time,  agriculture  will  furnish  the 
demand. 

Understands  that  the  Army  alone  will  need,  180,000  tons  of  nitric 
acid  in  time  of  war. 

Farmers  are  not  hacking  a  government  owned  or  governmont  ope  rated 
plant,  because  they  feel  that  the  processes  are  owned  hy  private 
•  persons,  and  the  patents  would  require  condemnation  and  confiscation. 
Furthermore,  the  efficiency  of  operation  of  a  private  owned  plant 
would  exceed  that  of  a  Government  operated  plant. 

The  cost  of  nitrate  of  soda  previous  to  the  war  was  from  )50.00 
to  $65 . 00  per  ton  delivered. 

The  South  is  impoverished  hy  the  scarcity  af  and  the  high  cost 
of  fertilizer. 

The  farmers  will  co-operate  with  the  Haval  Consulting  Board. 

States  that  the  Wise  Bill  only  authorizes  an  appropriation  for 
nitrogen  industry,  hut  is  not  well  drawn  and  not  complete.  The 
farmers  have  as  yet  produced  no  hill,  hut  are  working  on  one. 

Dr.  Baekeland  says  that  a  $4,000,000.00  plant  would  he  sufficient 
for  niixKfefcnx:  manufacture  of  nitrates  for  Government  retirements, 
and  wants  to  know  what  percentage  the  formers  would  he  able  to  take. 

6.  Mr.  Bower  says  that  the  experimental  time  for  the 
of  nitrogen  has  passed,  as  it  is  being  made  in  Europe 
quantity  and  cheap  price. 

Appointment  of  a  commission  only  means  delay  unless  the  commission 
works  in  a  hurry. 

Bpwer  has  a  personal  preference  for  the  oyanamid^rooess ,  although 
he  acknowledged  he  didn't  know  anything  about  it^comparod  with 
other  processes. 


in  commercial 


Dr.  Whitney  says  it  doesn't  maky  any  difference  what  process  we 
have,  as  long  as  we  make  nitrates. 

Dower  says  the  farmers  have  been  wanting  a  oheap  fertilizer  for  a 
long  time,  and  thinks  this  is  the  opportunity  for  the  farmers  and 
the  Hava 1  Consulting  Board  to  work  together  and  accomplish  what  eaoh 
desires  by  co-operation  and  on  the  same  hand  wagon. 

7.  Mr.  Addicks  asked  as  to  whether  the  farmers  were  interested  in 
getting  nitrates,  ot  simply  a  cheaper  price  for  nitrates  than  the 
present  market.  Bower  says  the  price  of  nitrate  of  soda  fixes  the 
prices  of  all  other  fertilizers,  and  they  are  interested  in  getting 
the  price  down.  .Farmers  have  paid  an  export  tax  to  Chile  of  S12.00 
per  ton  on  every  ton  of  nitrates  imported  to  this  Country  from 
Chile.  This  amounts  to  ^90, 000, 000.00  up  tp  the  present  time 

(did  not  say  from  what  date). 

8.  Dr.  Baekeland  says  that  the  cost  of  nitrates  to  farmers 
in  Europe,  at  the  close  of  the  war,  will  he  about  one-half  of 
what  Americans  have  to  pay  for  it  now. 

Owing  to  great  deposits  of  lignite  coal,  Germany  is  making  nitrates 
from  steam  power,  and  making  it  cheaper  than  we  are  paying  for  the 
nitrates  we  import. 

Bowers  states  that  the  fertilizer  business  is  in  a  state  of  great 
inefficiency  and  this  inefficiency  is  costing  the  farmers  millions. 
Heoited  the  manufacture  and  transportation  of  the  fertilizer  as 
it  is  now  furnished.  StateB  that  only  eighteen  percent  of  the- 
fertilizer  is  plant  food,  eighty-two  percent  is  absolutely  wotthr 
less  to  the  farmer.  He  is  interested  in  seoing  a  fertilizer 
through  the  ammonium  phosphate  prooess,  so  that  sixty  percent  of 
the  fertilizer  will  be  plant  food,  and  wants  us  to  please  help  to 
bring  this  shnuxi  about. 

9.  Dr.  Baekeland  said  that  the  Gormans  are  getting  a  higher 
yield  per  acre  than  the  United  States,  and  that  Belgium  is  getting 
higher  than  Germany.  The  Belgitan  yield  of  orops  per  acre  is 
proportional  to  the  nitrogen  fertilizer.  The  rental  per  annum 

of  farming  land  in  Belgium  is  as  high  as  the  price  of  land  per 
acre  (farming)  in  Amerioa.  So  Belgium  had  to  get  busy  and  improve 
her  fertilizer,  lluoh  of  the  fertilizer  in  Belgium  before  this  time 
jtHxiit  was  found  to  be  adulterated  horribly.  The  yield  per  aore 
in  Belgium  is  now  enormous. 

10.  Spencer  Miller  thought  the  Haval  Consulting  Board  wbb  getting 
far  afield  from  the  line  of  argument  regarding  munitions  of  war, 
and  Bower  states  that  they  will  look  after  the  farmer  end  of  it 
if  we  will  look  after  the  ftHxnxnaregfc  munitions  end  and  both 
working  together  oan  accomplish  results. 


11.  Mr.  Sperry  thinta  it  unwise  to  appoint  a  Board  or  Commission. 
Says  that  Herbert  Spenoor's  theory  regarding  hoards  still  holds 
good.  Suggests  a  hill. 

Mr.  Spraguo  and  others  do  not  agree  with  him  on  this,  and  a 
resolution  was  drawn  by  Mr.  Sprague,  which  has  boon  or  will  be 
transmitted  to  the  Secretary  of  the  Ilavy,  for  transmission  to 
tho  President  of  the  United  States,  requesting  that  a  commission 
be  appointed,  consisting  of  members  from  tho  Havy,  the  Army, 
Bureaus  of  Agriculture  and  Interior,  and  one  or  more  members  of 
the  Haval  Consulting  Board,  to  look  into  this  nitrate  question 
and  report  as  soon  as  possible. 

12.  All  the  above  took  from  11.00  A.  H.  to  1.00  P.  II. 

13.  Adjourned  at  1.00,  for  luncheon  at  tho  Engineers'  Club. 

AjTRBKUOII  SESSIOII 
Ho-oonvoned  at  2.06  P.  H. 

Motion  made  and  seoonded  that  tho  meetings  of  tho  Board  hereafter 
be  on  the  second  Saturday  of  each  month,  at  10.00  A.  II.,  and  at 
eaoh  meeting  the  place  of  tho  following  mootings  to  be  decided 
by  popular  vote.  Some  are  in  favor  of  holding  the  meetings  at 
the  Hew  fork  Havy  Yard.  Others  are  in  favor  of  holding  meetings 
at  the  Engineering  Building,  in  the  quarters  furnished  the  Board 
free  of  charge  by  the  Mining  Engineering  Society.  Mr.  Edison  fool 
that  it  would  be  better  to  hold  the  meetings  -  all  of  thorn  -  at 
tho  Brooklyn  Havy  Yard,  in  order  that  we  may  bo  kept  in  closer 
touoh  with  the  Haval  officers.  Some  of  the  Members  do  not  fool 
that  way  about  it,  as  the  Havy  Yard  is  inaccessible.  Personally, 

I  favor  tho  Havy  Yard,  beoauso  the  aooomodations  aro  superior, 
and  the  ventilation  of  the  room  very  superior.  If  left  to  their 
own  resources,  it  will  be  found  that  tho  quality  of  the  air  in  a 
room  varies  aonversoly  with  the  intelligence  of  the  mon  gathored 
therein.  Members  with  the  baldest  heads  insist  on  sitting  closest 
to  windows,  and  then  raise  a  howl  if  there  is  a  one-inch  oraok 
to  lot  some  air  in. 

BEPOlg  OP  COMMITTEES 

Aeronautics  -  Sperry,  Chairman. 

Committee  has  hold  no  meetings.  Mr.  Sperry  has  a  son  who  has 
been  flying  in  England,  Eranoo  and  Italy,  deports  tremendous 
activity  in  aeronautics  in  all  three  Countries.  Hight  flying  a 
new  feature  that  is  being  pushed  to  tho  utmost.  Aviators  are 
being  trained  to  fly  at  night.  Difficulty  has  been  and  is  being 
experienced  by  dvlators  in  Ice  oping  the  maohinos  on  oven  keol, 
when  flying  at  night.  Sperry  has  made  three  hundred  gyroscopic 
indicators,  all  or  most  of  which  are  now  in  the  hands  of  the 
Allies.  Sperry  thinks  wo  should  train  our  aviators  to  fly  at 
night.  Says  thore  is  a  Curtiss  school  aeroplane  engaged  in 


locating  dereliots  or  oortain  vessels  of  previously  unknown 
locations. 

"Drift"  ia  under  dovolonment. 

Germany  has  ordered  130  stabilizers,  but  Sperry  oannot  dolivor 
them. 

Committee  on  Standardization,  eto.  -  Coffin,  Chairman. 

States  the  work  of  his  committee  1b  divided  into 

(a)  An  inventory  of  what  country  oould  lop  oral  upon, 

(b)  Arrangement  of  affairs  in  ;7ashington,  so  that  tho  Army  and  Davy 
oould  go  out  and  take  advantage  of  such  inventory  by  avoidance  of 
tho  rule  pertaining  to  tho  giving  of  all  business  to  tin  lowest 
bidder,  so  that  souroos  of  supply  from  many  quarters  can  be 
aouragod  on  a  small  scale. 

(c)  2 he  lining  up  of  tho  labor  element  in  the  formation  of  the 
industrial  reserve. 

The  five  national  technical  organizations  have  received  acceptances 
from  all  the  men  who  have  been  asked  to  serve  a3  State  Directors, 
and  these  State  Directors  will  be  appointed  by  tho  Seorotary  of 
the  Davy  in  duo  time.  Out  of  the  ontire  list  of  about  tv©  hundred, 
only  two  declined.  One  of  these  two  is  doad.  and  tho  other  had  to  ' 
decline,  booause  of  unsurmountable  obstacles. 

Coffin  has  received  many  requests  as  to  tho  political  significance 
of  this  mobilization  move.  Says  this  Board  must  avoid  all  semblance 
of  Politics  if  results  are  to  bo  aohievod  for  tho  good  of  tho 
Country. 

After  legislation  to  froe  the  hands  of  tho  Atmy  and  Havy  heads, 
a  bill  ha3  been  introduced  to  empower  tho  President  to  authorize 
the  Secretaries  of  tho  Army  and  ilavy  to  plaoe  trial  orders  of 
apparatus  and  material,  on  equitable  business,  to  develop  inde¬ 
pendent  pouroos  of  supply  to  produce  any  reasonably  small  order 
for  material ,  eto .  This  to  apply  only  on  small  ordors. 

On  the  labor  end  -  is  in  close  touoh  and  apparently  thoro  are  no 
sorious  complications.  Several  strong  arguments  that  please  labor. 
The  laboring  man  ia  moot  intorestod  in  having  a job  to  hold,  and 
of  holding  it  after  he  gots  it.  If  war  is  declared,  about  /  of 
the  industries  would  go- flat  and  hundreds  of  thousands  of  men 
would  ho  laid  off.  Those  who  aro  oompotont  to  produce  ammunition 
would  he  running  day  and  night.  Enrollod  labor  in  tho  industrial 
reserve  would  not  he  subject  to  draft  for  enlistment  in  tho  Army 
and  Davy. 


Bankers  are  not  only  interosted  in  tho  prosperity  of  the  Country, 
hut  also  interested  in  kooping  the  big  industries  in  private 
hands ,  rather  than  Government  ownership.

Wr.  Coffin  showed  samples  of  completed  four-page  formB,  airailar 
to  the  censor  a  forms,  to  be  used  in  classifying  the  industries, 


Both  the  Army  and  liavy  have  authorized  the  Bonding  of  Offioors 
to  Detroit  for  education  in  the  design,  building  and  testing  out 
of  hydro-carbon  engines. 


Coffin  states  that  about  two  woolcs  ago,  the  delegation  of  adver¬ 
tising  men  waited  on  the  Prosidont,  and  placod  at  his  disposal 
free  of  charge  to  the  Government,  their  facilities  for  getting’ 
advertising  space,  writing  the  ads,  etc.,  etc.  along  preparedness 
and  alliod  patriotic  lines,  patriotic  basis.  Tho  Prosidont  re¬ 
ferred  these  men  to  the  Secretary  of  tho  iiavy,  who  in  turn  re¬ 
ferred  them  to  the  Ilaval  Consulting  Board.  Saundors  met  them  in 


Tho  advertising  men,  about  nine,  were  invited  to  oome  in  and 
discuss  the  matter  of  publicity,  etc.  with  tho  entire  Board.  It 
is  unanimously  thought,  wise,  desirable  and  absolutolv  necessary 
to  carry  the  message  of  what  tho  Board  is  trying  to  acoonrolish 
to  everybody  in  the  United  States.  The  Board  now  has  with* it  those 
advertising  men,  the  national  Chamber  of  Commerce,  and  the  labor. 

Bnterwjthe  advertisers,  about  nine  in  all. 


kr.  Houston,  President  of  the  Associated  Advertising  Clubs  of 
the  world,  and  whioh  includos  all  the  principal  advertising 
writors,  illustrators,  sollorB  and  buyers  -  15,000  men  in  all. 

Mr.  Houston  says  that  all  tho  national  defense  sooietioa  have 
Deon  trying  <feo  enliat  tho  norvioos  of  this  associated  advertising 
olfcb,  but  upon  investigation,  found  that  oaoh  of  those  societies 
has  somo  axe  to  grind.  Furthermore,  this  associated  advertising 
club  of  tho  world  thinks  they  aro  big  onough  uud  imnortunt  onoiigh 
sinooro  onough  and  patriotic  onough,  to  v.arit  to  doal  with  head-'-  ’ 
quarto  rs. 


The  chairman  callod  attention  of  tho  advertising  mon  to  tho  faot 
that  this  Board  is  absolutely  non-partisan,  politically.

His  club  is  going  to  ask  the  billboard  and  other  advertising 
space  sollors  to  oontrihute  space  to  Haval  Consulting  Board 
propoganda,  as  will  bo  put  out  from  time  to  time. 


Sverybody  aoema  to  bo  unanimous  in  wanting  to  have  the  Naval 
Consulting  Board  and  subsidiary  groups  authorized  by  Congress. 

Mr.  Houston  says  they  want  the  publicity  group  to  be  an  arm  or 
the  Naval  Consulting  Board,  and  nothing  oan  bo  done  without 
authorization  from  Congress. 

Mr.  Houston  says  wo  have  sixty  percent  of  the. industries  of  the 
World  in'  the  United  States.  Publication' of  this  faat,  baolcod 
up  by  proof,  will  go  a  long  way  toward  impressing  upon  foroignors 
that  they  had  best  keep  their  hands  off  America. 

Br.  Whitney-  expressed  his  personal  gratitude  to  those  gentlemen. 
A3ks  if  the  Advertising  Club  could  boost  the  Naval  Laboratory 
and  nitrate  industry  propogonda. 

Mr.  Houston  says  the  advertising  committee  would  work  in  close 
oollaboration  with  the  headauartors  of  the  Naval  Consulting 
Board,  and  would  go  after  what over  was  thought  by  the  Board 
to  bo  most  important  to  have  put  before  tho  public. 

Mr.  Sperry  called  attention  to  tho  fact  that  tho  Naval  Consulting 
Board  is  not  authorized  as  yet, and  suggests  that  someone  should 
proaoh  tho  wisdom  of  tho  establishment  of  such  a  board. 

Mr.  Houston  says  that  publioity  will  see  to  it  that  tho  Board 
is  continued  in  its'  work. 

Dr.  Baekeland  wanted  to  know  where  and  haw  tho  advertising  club 
expeots  to  raise  tho  money  necessary  to  conduct  such  campaign. 

Mr.  Houston  replied  that  if  tho  Board  and  the  advertising  club 
as  an  arm  of  tho  Board  is  authorized  by  Congress,  they  will 
go  to  the  controllers  of  advertising  space  in  axnii  this  country, 
and  feels  quite  sure  that  those  advertising  apace  collars  will  _ 
ba  glad  to  respond,  without  cost  to  the  Government. 

Mr.  Gudo,  the  billboard  advertising  man  in  How  fork,  made  on 
address.  Ho  says  tho  advertising  asoooiation  includes  tho 
advertising  men,  tho  business  men,  eto.  in  every  town  and  oity 
in  the  United  States. 

Mr.  Coffin  introduces  a  Mr.  V.’olls,  whom  I  understood  to  bo  the 
head  of  some  large  manufacturing  concern  which  is  oompotont  to 
make  war  munitions,  ote. 

Mr.  Wells  seys  it  would  take  kratt  and  Whitney,  Brown  and 
Sharpe,  and  his  concern,  five  yoars  to  make  the  necessary  gauges 
to  enable  200,000  shells  per  day  to  be  turned  out. 

If  the  gauges  are  not  used,  all  sorts  of  trouble  arises  in 
shooting  of  the  shells  from  guns. 


To  make  1,000  fuses  per  day,  in  oaoh  of  sis  factories,  would  oost 
'146,000.00  for  gauges  alone. 

There  have  boon  oontraotg  let  for  fuses  at  from  11 . 00  to  023. 00 
each. 

The  Government  should  own  all  the  blueprints,  gauges,  tools,  etc. 
so  that  within  forty-eight  hours  they  could  start  to  malting 
ammunition  in  the  privately  ownod  plants,  as  well  as  Govern  men', 
arsenals. 

There  should  be  a  capacity  of  ..00,000  shells  per  day,  of  various 

Si  208. 

Ho  one  on n  start  to  make  fuses  iwithout  gaifres.  All  the  munition 
manufacturers  are  busy,  after  all  thi3  time,  trying  to  make  gauges 
so  that  thoir  rejection  of  ammunition  will  bo  out  down. 

What's  the  use  of  the  Array  and  the  llavy  without  ammunition. 

uno  of  the  most  important  things  on  the  oalendar  at  prosent  is 
to  get  a  lot  of  gaugos  made  up  of  the  different  sizes  of  fuses 
and  shells,  to  a  total  of  200,000  shells  of  various  sizes  per 
day,  and  put  these  away  in  storage,  using  them  only  to  educate 
men  to  go  out  and  make  shells  in  privately  owned  factories. 

The  value  of  the  gauges  alone,  to  manufacture  200,000  shells  por 
day,  -would  cost  bo two on  neventoon  million  and  twenty  million 
dollars. 

Gauges  wear  out  quiokly  and  should  bo  replaced  immediately 
they  become  worn  beyond  the  limit.

Hr.  J.liller  suys  that  if  war  should  come  on,  this  country  would 
probably  stand  one-quarter  of  its  national  woalth  before  the  war 
ended.  This  moans  one-quarter  of  the  personal  wealth  of  eaoh 
individual  in  the  United  States.  The  itavy  costs  only  '‘1.60  per 
capita  per  annum  nor;,  and  for  the  small  amount  of  throe  dollars 
per  oapita,  wo  could  double  the  llavy  upkeep,  i.  o.  to  pay  for 
twice  as  large  a  llavy  as  wo  have,  in  upkeop.  Ho  one  hut  a  fool 
would  profor  the  risk  of  having  to  give  up  one-quarter  of  his 
ontiro  wealth,  if  tho  country  oan  bo  insured  against  invasion 
by  an  adequate  llavy  nt  three  dollars  per  year  tax  on  oaoh  man. 

Mr.  Coffin  introduced  another  gentleman , who  is  at  the  head  of 
the  "ihnorioan  Machinist"  publication. 


-9- 


Thia  gentleman  says  that  the  "American  Machinist"  is  ready  to 
spend  between  030,000.00  und  040,000.00  to  present  the  details  of 
ammunition  manufacture,  through  his  paper,  froe,  on  the  basis  of 
his  publioation  getting  the  neoossary  data  (such  as  in  not  deoret) 
from  the  Bureau  of  Ordnance  of  tho  Davy,  and  tho  Ordnance  Depart¬ 
ment  of  tho  Array,  so  that  an  intelligent  series  of  articles  ofih 
be  written  that  will  bo  of  much  value  to  tho  thousands  of 
machine  shops  that  subscribe  to  tho  "American  Machinist". 

Mr.  Coffin  was  much  impressed  with  tho  importance  of  ao-opc  rating 
with  this  gentleman,  saying  that  the  way  to  gat  action  is  to  get 
busy  and  use  all  the  facilities  placed  at  our  command  or  which 
we  con  ha vo  placed  at  our  command. 

Mr.  Sperry  says  that  if  4,000  or  5,000  machine  shops  got  posted 
on  how  to  manufacture  ammunition,  it  will  a  stride  forward.  Says 
the  "American  Machinist  '  roaohos  every  ono  of  th030  ships  ,  and 
is  hotter  than  any  other  publication. 

General  discussion  arose  as  to  what  oxtent  tho  information  that 
is  now  being  srainod  by  manufacturers  of  munitions  in  supplying 
said  munitions  to  foreign  powors,  will  be  of  any  aorvioo  to  us  in 
time  of  war.  Tho  impression  scorns  to  bo  that  tho  foreign  arm  unit  ion 
varies  considerably  Prom  the  American  ammunition. 

Mr.  taorame  has  to  say  in  this  connection,  howovey,  that  ho  fools 
tho  shoos  now  making  ammunition  nro  protty  wo  11  on  to  it,  and  that 
inability  of  tho  oditor  of  tho  "American  Machinist"  to  got  tho 
kind  of  information  he  wantod  was  tho  disinclination  on  the  part 
of  taaa  oompany  to  spond  a  lot  of  monoy  fin-ling  out  how  to  do  a 
thing,  to  freely  discloso  all  rlotails  to  tho  print.- 

Mr.  Saundora  says  tho  Secretary  of  the  Davy  is  ranking  an  effort, 
through  certain  parties,  to  havo  the  Board  legalized  and  get 
rnonoy  for  expenses  of  the  Board. 

Coffin  says  tho  Secretary  of  tho  iiavy  says  that  if  tho  Chairman 
of  euoh  sub-committee  will  make  out  a  list  of  the  things  his 
committee  has  aooomoi inhod,  and  what  hie  oommittoo  hopo3  to 
accomplish,  and  sond  it  to  tho  Secretary  of  tho  Iiavy  through  our 
Secretary,  considerable  assistance  y;ill  be  rondorod  in  the  mattor 
■of  tho  laboratory, v3b?i  the  legalising  of  the  Iiaval  Consulting 
Board  aomos  up. 

It  was  so  ordered. 

Mr.  Sperry  alluded  to  the  groat  response  of  tho  engineers  of  the 
Country  when  this  Army  agitation  started  up.  Mach  of  the  meetings 
at  the  Engineering  Building  has  been  greatly  overcrowded,  a 
second  meeting  each  week  having  to  bo  held  as  un  overflow  mooting, 
to  accomodate  those  who  v/antod  to  he  present.  Mr.  Sperry  wants 
to  know  why  some  of  this  enthusiasm  and  patriotism  cannot  he 
directed  toward  the  Havy. 


-10- 


Says  tho  Mavy  has  ten  uses,  to  the  Arm one,  for  on  engineer. 

lir.  Sperry  says  that  at  the  Philadelphia  Yard  there  are  sovoral 
ships  that  are  deteriorating  from  laolc  of  jsse ,  as  will  uny 
pieoe  of  apparatus  deteriorate  when  put  out  of  commission,  eto. 
Says  why  not  appoint  a  committee  to  see  what  can  ho  done  toward 
training  of  engineers,  eto.  on  hoard  those  obsolete  but fcleshipa , 
in  the  Summer  months ,  as  tho  Army  is  doing  at  Plattsburgh  with 
the  Army  recruits. 

It  was  moved  and  seconded  that  in  future  a  general  discussion 
of  the  Board  bo  not  recorded  and  transcribed,  only  the  actions 
taken  by  the  Board  to  bo  transcribed. 

After  sovoral  discussions  of  a  minor  nature,  tho  Board  adjourned 
at  4.45  P.  M.

My  dear  Mr.  Edison:- 

I  send  you  herewith  a  copy  of  letter  to  Hr .Daniels 
concerning  a  matter  in  which  I  would  he  very  much  obliged  if  you 
would  give  me  some  help. 

The  invention  mentioned  in  this  letter  is  an 
induction  generator  motor  combination  which  effects  a  2  to  1 
speed  induction  with  only  half  the  power  transmitted  electrically 
and  no  moving  contracts.  I  am  sending  you  a  drawing  and 
description  which  will  make  its  details  clear. 

I  want  to  formally  submit  this  design  through  the 
Consulting  Board,  but  my  first  need  is  to  get  an  opportunity  to 
build  the  apparatus  which  will  establish  a  big  advance.  Fifty 
similar  boats  are  included  in  the  new  Havy  programme. 

Very  truly  your  s ,

Dear  Sir:- 

I  have  Just  heard  from  Mr.  Hardesty  that  it  is 
reported  that  the  machinery  for  the  Mare  Island  destroyer  was 
to  "be  "built  at  the  Yard,  ana  I  want  very  much  to  take  enough 
of  your  time  to  call  your  attention  to  features  of  thiB  case 


whioh  you  may  not  know. 

0u±  hid  for  the  apparatus, delivered  at  the  Yard, 

_ _ §128,000.00 

including  superintendence  and  §3,156.  for  spare  parts. 

The  Yard's  estimate  was 

Labor — - §23,900. 

Indirect - 8  6,800. 

Material - §88.300. 


This  figure  does  not  include  royalty  to  Parsons, 
and  with  this  added,  I  think  the  figure  will  he  higher  than  ours. 

I  think  their  royalty  is  fifty  centB  per  H.P. .which  would  he 

§10,000. 

Our  proposal  embodies  a  valuable  invention  of 
mine  whioh  I  made  as  a  member  of  the  Haval  Consulting  Board  in 
direct  response  to  one  of  the  needs  whioh  were  given  to  us  shortly 


[ATTACHMENT/ENCLOSURE] 


after  our  first  moating. 

This  invention  relates  to  the  method  of  coupling 
cruising  turbines  ana  accomplishes  two  very  useful  purposes  in 
a  very  simple  and  reliable  manner. 

Owing  to  the  virtue  of  this  arrangement  and  to 
the  very  high  quality  of  the  turbines  which  we  proposed,  our 
proposal  offers  to  guarantee  results  vastly  better  than  any  ever 
produced  in  such  a  vessel.  At  a  cruising  speed  of  12  knots 
our  steam  consumption  is  less  than  half  that  offered  by  the 
WeBtinghouse  Company  in  a  competitive  proposal,  ana  it  is  pre¬ 
sumable  that  our  superiority  over  the  equipment  proposed  by  the 
Havy  Yard  is  also  very  great. 

We  have  boon  informed  that  equipment  for  a  similar 
boat  at  H  or  folk  has  been  ordered  from  Bath  at  a  price  higher  than 
ours  and  with  guarantees  much  inferior  to  ours.  We  were  not 
allowed  to  bid  on  this  boat  although  we  tried  very  hard  to  got 
permission  to  do  so. 

The  equipment  which  wo  offer  in  this  case  without 
tho  cruising  turbine  arrangement, which  we  add,  is  unquestionably 
bettor  than  the  Bath  equipment  and  on  that  basis  the  price  could 
be  much  reduced. 

In  this  destroyer  matter  we  have  been  held  off 
for  months  and  yearB  and  in  tho  meantime  our  case  has  steadily 


[ATTACHMENT/ENCLOSURE] 


strengthened. 

The  Parsons  people  in  this  country  are  working 
through  every  possible  channel,  political  and  otherwise,  to  keep 
their  designs  in  UBe  in  our  Havy  and  they  seem  to  get  much 
support  from  many  of  our  officers* In  the  meantime,  Yarrow  and 
many  of  the  best  foreign  builders  of  such  boats,  have  gone  to 
impulse  turbines. 

For  a  long  time  we  have  been  promised  an  oppor¬ 
tunity  to  bid  on  this  Mare  Island  boat.  We  have  made  the  lowest 
bid  and  offered  the  best  guarantees, and  I  feel  that  we  are 
entitled  to  the  award. 

.,Very.  truly  yours.

pr.ope-J.lor  shaft  through  gearing  of  the  special  type  developed 
’ey  the  General  Electric  Company.  With  each  main  turbine  u 
cruising  turbine  is  installed „  the  connection  between  the  main 
turbine  and  the  cruising  turbine  being  accomplished  by  electri¬ 
cal  means  through  an  arrangement  which  nay  be  described  as  a 
speed  reducing  clutch.  The  main  turbine  will  consist  of  v. 
succession  of  wheels,  each  wheel  carrying  a  single  row  of  b lad  an, 
These  wheels  are  separated  by  diaphragms  with  nozzles  oxtonfling 
entirely  around  the  periphery  of  all  wheals.  '  The  pitch  diameter 
of  these  wheels  increases  progressively  fren  the  high  pressure 
end  to  the  low  pressure  end,  all  whool3  being  proportioned  for 
the  maximum  of  bucket  efficiency  and  the  minimum  of  frictional 
rotation  loss,  Two  points  of  steam  admission  are  provided  in 
each  of  these’  main  turbines  which  nonnoob  to  the  first  nr.d-  third 
stages.  At  the  maximum  speed  of  the  vessel  the  steam  will  be 
admitted  to  the  third  stage.  At  somawliat  loner  speeds  it  will 
be  admitted  to  the  first  stage  of  tho  main  turbine  and  at  still 
loner  speeds  it  will  pass  through  tho  cruising  turbine  before 
entering  the  main  turbine.  The  admission  of  steam  as  dosirad  will 
be  oontrolled ■ by  suitable  hand  operated  valves  and  oentrifural 
devices  will  be  provided  on  both  the  main  and  pruning  turbines 
which  will  olose  a  valve  in  the  main,  steam  admission  in  case, 
for  any  reason,  the  turbine  should  run  above  normal  spood.

The  pruiaing  turbine  will  consist  of  a  similiar 
group  of  wheels,  each  having  a  single  row  of  blades  with 
steam  admission  all  the  way  srouhg,  and  in  addition  to  this 
there  will  be  a  single  stage  carrying  two  rows  of  blades  with 
steam  admission  covering  only  a  part  of  the  periphery,.-  l'his 
first  two-bucket  stage  will  be  used  only  at  very  low  speeds 
when  the  steam  flow  is  small, 

She  speed  reducing  clutch  oonsiots  of  an  induction 
generator  and  a  synchronous  motor,  the  corresponding  ne^ts 
of  which  are  mounted  upon  the  same  shaft  and  connected  to¬ 
gether  through  an  axial  hole  in  the  shaft  s  this  shaft  being 

coupled  to  the  main  turbine a  The  generator  element  of  this

combination  is  surrounded  by  an  fasfrnytfal  squirrel-cage  ravol- 
vin^  "element  which  is  carried  by  the  shaft  of  the  cruising 
turbine.  She  motor  element  is  sitrrounded  by  a  stationary 
field  structure  which  is  energized  by  diroot  current  from  the 
lighting  circuit,  of  the  vessel. 

When  both  turbines  are  in  motion  and  the  motor  field 
is  suitably  energized,  an  olectrioal  relation  is  established 
by  whioh  the  ornising  turbine  operates  vary  slightly  above 
twice  the  speed  of  the  main  turbine.  About  half  the  power  of 
the  cruising  turbine  is  delivered  direct  to  the  main  tureino 
shaft  throxigh  the  torque  of  the  induction  generator,  The  re¬ 
mainder  of  the  power  of  the  cruising  turbine  is  turned  into

Dear  Mr.  Edison: 

You  will  doubtless  remember  the  former  communication 
of  Lieutenant  Gillmor,  of  London.  I  have  recently  received 


a  letter  from  him  containing  the  enclosed  excerpt  bearing 
on  our  matters,  which  I  take  the  liberty  to  hand  you, 
thinking  it  may  be  of  interest. 

It  seems  to  me  that  the  point  Mr.  Gillmor  raises  with 
reference  to  the  Board  aiding  the  Navy  to  make  connections 
with  the  great  technical  as  well  as  organizing  resources 
of  our  country  might  be  followed  along  technical  lines  in  a 
manner  similar  to  that  in  which  Mr.  Coffin's  Committee  on 
industrial  organization  is  accomplishing  splendid  results. 

I  have  no  doubt  that  the  industrial  institutions 


having  technical  experimental  resources  would  be  as  glad  to 
aid  us,  should  they  be  called  upon  for  specific  service,  as 
the  Western  Electric  Company  was  to  aid  the  British  Board. 

Yours  very  truly,

Excerpt  from  Letter  of  March  3,  1916,  from 

R.  E.  Olllmor,  London,  to  Elmer  A.  Sperry. 

"I  was  very  glad  to  hear  that  my  suggestione 
as  to  the  organization  of  the  Naval  Advisory  Board, 
were  found  to  be  Interesting  and  of  some  possible  value, 

I  feel  very  strongly  that  not  only  the  country,  but  the 
Navy  Itself,  must  be  waked  up  to  their  reponslblllty 
for  preparedness. 

"The  great  ambition  of  the  Naval  Advisory  Board 
should  be  to  connect  the  Navy  with  the  great  technical 
and  organizing  resources  of  our  country,  and  in  this  way 
help  them  to  solve  their  problems  of  technique  and 
organization.  The  Navy  is  not  a  mystery  of  the  sea;  it 
is  simply  a  great  organization  involving  many  technical 
and  organizing  problems,  which  must  be  solved  to  gain 
the  maximum  efficiency. 

"The  British  Board  of  Inventions  has  gradually 
expanded  until,  I  believe,  it  is  now  accomplishing  a 
very  useful  function.  I  had  a  talk  with  Mr.  Wilkins 
last  week  in  regard  to  thiB,  and  he  told  me  that  the 
inventions  Bureau  had  come  to  him  for  the  solution  of 
several  problems  and  had  been  more  than  glad  to  take 
advantage  of  the  experimental  resources  of  his  Company. 
(This  refers  to  the  'Western  Electric  Co.)  The  principal 
problem  they  brought  to  him  was  the  detection  of  the 
approach  of  Zeppelins  and  submarines  from  a  distance. 

"Some  time  ago  you  sent  me  a  copy  of  a  letter  to 
your  Committee  of  the  Naval  Advisory  Board  respecting 
aids  to  navigation.  At  the  time  I  had  nothing  to  suggest 
in  regard  to  this.  If  anything  comes  to  mind  I  certainly 
will  report  about  it." 


As  his  mission  cannot  succeed  in  a  degree 
sufficient, to  insure  satisfactory  completion  of  im¬ 
portant  parts  of  our  work  without  the  co-operation  of 
representative  Americans  resident  in  England,  it  is 
obviously  necessary  Miat  he  be  placed  in  satisfactory 

It  would]  bo  of  material  assistance  to  have 
Paymaster  Tobey  connected  through  your  agency  with 
such  of  your  representatives  abroad  as  you  may  name, 
and  it  would  be  a  mark  of  your  great  interest  in  our

from  this,  the  present  bank  balance  is  only  $66.25.  As 
thiB  balance  will  be  wiped  out  upon  settlement  of  the 
unpaid  bills  amounting  to  $70.63,  it  will  be  necessary 
that  each  member  make  a  further  contribution  of  $10.  to 
cover  future  expenses. 

I  would  therefore  be  obliged  if  you  would  kindly 
send  me  your  oheok  for  $10. ,  made  payable  to  the  Haval

Re sear oh

proposition  to  yovu 


earoh  worS^jfrom  the  standpoint  of  nationai*,c(u£y^  and 
may  appeal  to  you,  so  I  beg  to  submit  the  following^ 
o  your  oareful  consideration. 


At  the  present  time  the  raw  materials  for  high  explosives 
such  as  glycerine,  oarbolic  acid  and  toluol,  are  both  scarce  a»4^ 
expensive;  hence  the  explosives  made  from  the  products  derived  ^ 
from  these  compounds  are  naturally  scarce  and  expensive.  Instead 
of  separating  from  the  cbal  tars  these  different  chemioals  and. 
purifying  them  at  considerable  expense,  I  take  the  entire  distillate 
from  the  tars  and  treat  the  same  with  the  neoeseary  ohemioals,  and 
obtain  a  product  whioh  has  powerful  explosive  properties,  whether 
it  is  used  alone  or  mixed  with  other  ingredients.  .The  process  of 
manufacturing  is  comparatively  simple,  and  the  total  cost  of  manu¬ 
facture  would  not  exceed  6 <p  per  pound,  while  the  explosive  com¬ 
pounds  in  the  market  are  rather  expensive  in  comparison  with  this. 

The  explosives  made  with  this  oompound  are  what  is 
commonly  called  "safety"  explosives,  used  in  blasting  and  in  ooal 
mines.  There  1b  safety  not  only  in  manufacturing,  but  also  in 
handling  and  transporting  the  same,  without  incurring  the  dangers 
attached  to  nitro-glyoerine  and  piorio  acid  accidents  and  diiii- 
oulties. 

As  a  oommeroial  proposition  this  process  may  appeal  to 
you  strongly  because  some  of  the  maohinery  employed  in  the  manu¬ 
facture  of  war  materials  could  be  used  advantageously  in  connection 
with  this  proposition.  Again,  the  raw  material  is  so  abundant 
and  oheap ,  that  is,  the  oils  whioh  we  can  get  at  a  cent  a  pound, 

I  oannot  see  any  difficulty  at;5all  in  manufacturing  this  product. 
Should  you  be  interested’ to  look  into  this  matter,  I  will  be 
pleased  to  oome  down  and  see  ybu  and  go  into  further  details  with 
you.  .  ,

To  the  members  of  the  Hava!  Consulting  Board- 
Bear  Sirs: 


May  26,

Jor  your  information  I  quote  below  extraot^^irom  the  Report  of 
the  Committee  on  Naval  Affairs  of  the  House,  to  accompany  H.  R.  16947 : - 

/ 

Naval  Consulting  Board 

When  the  Navy  Department  learned  how  far  behind  some  of  the 
belligerent  nations  were  in  the  manufacture  of  munitions  for  war, 
the  Secretary  of  the  Navy  concluded  that  real  preparedness  re¬ 
quired  that  an  attempt  should  be  made  to  mobilise  the  industries 
of  the  United  States,  as  well  as  to  provide  means  for  military  and 
naval  preparations.  He  appointed  a  civilian  naval  consulting  board, 
of  which  Mr.  Thomas  A.  SdiBon  was  made  chairman-  Theae  gentlemen 
were  appointed  by  the  various  engineering  societies  of  the  United 
States  and  have  volunteered  their  eervioes-wlthout  oost  to  the 
Government  thus  far  and  have  been  performing  suoh  important  work 
that  the  Secretary  of  the  Navy  and  the  committee  on  Naval  Affairs 
deem  it  proper  that  the  actual  expenses  incurred  by  members  of  this 
board  should  be  paid  by  the  Government,  although  no  compensation 
for  their  services  is  reoonanended-  The  committee  reoommendB  in  the 
bill  the  ereotlon  of  an  experimental  laboratory  for  the  uee  of  the 
Naval  Consulting  Board  as  elsewhere  described  in  this  report  and 
it  1b  believed  that  these  eminent  engineera  serving  in  an  advisory 
oapaolty  will  be  of  great  assistance  to  the  naval  experts  in  solving 
some  of  the  very  grave  problems  of  the  profeBBion,  such  as  the 
problem  of  the  erosion  of  the  guns,  motors  for  aeroplanes,  engines, 
and  batteries  for  submarines,  and  the  very  large  problem  of  the  or¬ 
ganisation  of  the  industries  of  the  country  eo  that  in  time  of  war 
they  oould  easily  be  adjusted  to  make  munitions-  The  object  of  this 
Naval  Consulting  Board  ie  to  create  euoh  a  potentiality  for  manufac¬ 
ture  of  munitions  that  the  organisation  will  be  perfected  so  that 
almost  automatically,  upon  the  declaration  of  war  or  in  oase  of 
national  emergency,  the  vast  industrial  resouroes  of  the  country 
will  begin  the  manufacture  and  delivery  of  munitions  of  war- 

While  it  is  recognized  that  many  of  the  naval  Inventions  have  been 
created  by  navel  experts,  yet  civilian  inventors  and  civilian  engin¬ 
eers  have  given  to  the  Navy  some  of  its  greatest  improvements  -  It  is 
the  opinion  of  the  committee  that  the  use  of  euoh  inventive  genius 
should  be  obtained  for  the  proper  development  and  progress  of  prepar¬ 
edness,  and  the  committee  adopts  the  reoommendatlon  of  the  Secretary 
of  the  Navy  that  $26,000  be  appropriated  to  pay  the  actual  expenses 
Incurred  by  and  in  oonneotion  with  the  civilian  Naval  Consulting  Board.

Experimental  Laboratory 


An  appropriation  of  §1,000,000  is  recommended  for  an  "experimental 
laboratory"  to  ooet  not  exceeding  $1,600,000.  The  oommittee  had 
before  it  many  distinguished  engineers  oomposing  the  Haval  Consulting 
Board,  including  Hr-  (Thomas  A-  Edison.  As  heretofore  stated,  that  in 
the  interest  of  preparedness  and  in  an  attempt  to  perfect  a  mobilisa¬ 
tion  of  the  industrial  interests  of  the  United  States,  the  oommittee 
reoommends  the  ereotion  of  this  laboratory  in  order  that  the  multitu¬ 
dinous  different  details  oonneoted  with  supplies  for  the  Havy  might 
be  perfected  for  one  unit  of  all  war  machinery  and  to  do  it  with  the 
greatest  possible  rapidity.  (PhiB  laboratory  would  standardise  as  far 
as  possible  all  parts  of  all  machinery  used  in  war  and  would  exper- 
lment  with  the  practical  work  of  soieAtifio  development  of  the  art  of 
war  as  regards  the  maohinery  pertaining  thereto.  It  would  have  to  do 
with  the  praotioal  working  out  of  soientifio  deductions  that  have  not 
passed  the  theoretical  experimental  stage.  .  ... .  „ 

Hr.  Edison,  at  his  own  personal  oost,  submitted  plans  of  buildings 
in  great  detail  which  if  oohstruoted  would  be  of  oonorete  and  like  a 
modem  manufacturing  building  of  plain  construction.  The  plans  sub¬ 
mitted  showed  in  detail  whereby  the  various  units  of  maohinery  for 
warfare  might  be  produoed  and  standardiaed'.'-such  as  aeroplanes,  range 
finders,  submarine  engines,  small  guns^djmws^ning  relating  to  war 
maohinery.  By  these  means  eaoh  unit /opuAd-  be^pbr^eoted,  the  gauges 
produoed,  and  arrangements  made  with /various  shbppX throughout  the 
oountry,  so  that  on  telegraphio  notihf»the  various,  Wilts  could  be  man¬ 
ufactured.  It  is  not  intended  that  /a  Ur eat  /faumbef  tot  any  unit  should 
be  manufactured  at  any  time,  but  that V$hQ; gauges ,£j«to . ,  be  so  perfec¬ 
ted  that  the  potentiality  of  having  the-tu)i,tB.  mad«f  dt  ahort  notice  will 
be  provided  for.  The  laboratory  will  b^equipped.with  many  different 
toolB,  but  they  will  be  of  standard  make/  -capable  of  making  plmoBt 
any  motion.  Ab  soon  as  any  unit  of  war  ma'ahiiftdry  1b  perfected  by  thiB 
laboratory,  specifications  can  be  oarefully  drawn  so  that  the  commer¬ 
cial  enterprises  of  the  oountry  can  and  will  know  definitely  that  the 
work  oan  be  done.  This  will  interest  and  tend  to  mobilize  the  in¬ 
dustrial  interests  of  the  United  States.  Contractors  will  know  that 
there  is  no  risk  in  taking  the  oontraot,  Binoe  the  laboratory  has 
perfected  the  unit  in  question,  and  in  oonBequenoe  of  vrtiioh  oon®eti- 
tion  will  result  and  the  Government  will  be  able  to  obtain  war  material 
and  maohinery  at  a  greatly  reduoed  prioe.  .  ...  .  .. 

A  great  advantage  thiB  Government  laboratory  will  have  will  be  the 
assistance,  without  oost  to  the  Government,  of  the  various  societies 
of  meohanioal  and  ohemioal  engineers,  as  well  as  civil  engineers  of 
the  United  States,  comprising  in  all  about  30,000  engineers,  all  of 
whom  are  willing  to  render  patriotic  service  in  a  scientific  way 
without  oost  to  the  Government-  The  committee  therefore  in  the  in¬ 
terest  of  real  preparedness  reoommends  this  appropriation  to  the 
favorable  consideration  of  the  House.

the  same  sort  of  data  from  several  manufacturing  concerns  in

Bear  Sir: 

|  have  received  your  favor  of  the  29th  ultimo, 
also  copy  of  application  for  patent  to  provide  for  the 
running  of  a  submarine  helot;  the  surface  of  the  water  with 
its  gasoline  or  oil  online. 

In  my  opinion  there  would  ho  too  much  "wake". 
However,  I  shall  send  your  letter  ana  the  specifications  to 
the  Secretary  of  the  liaval  Consulting  Board,  who  will  for¬ 
ward  it  to  the  proper  committee  for  c one i deration.

Dear  Sir:-

I  have  your  letter  of  July  3rd.  and  thjink  you  for  offering  ! 
to  present  what  I  had  to  communicate  to  the  Secretary  of  the  .  ^  <>-/- 

V^vJ  K*-*.  rp-- 


Naval  Consulting  Board. 


You  Bay  in  your  letter  that  in  your  op inioIJf^e£f 
too  much  "Wake",  and  in  regard  to  this  would  say  that  I  am  perfectly  ^ 
sure,  from  experiments  made  in  the  past,  that  there  will  be  no  wake 
qt  all,  because  the  products  of  combustion  when  liquified  oxygen  is 
used,  are  water  and  carbonic  acid.  The  water  will,  of  course,  at  once 
condense,  and  the  carbonic  acid  will  be  thoroughly  absorbed  in  the 
sea  water,  owing  to  the  fact  that  it  is  ejected  into  the  surrounding 
water  in  the  form  of  almost  micropBCopical  bubbles,  which  will  quick¬ 
ly  absorb  in  the  great  mass  of  sea  water,  particularly  when  aided  by 
the  swirling  of  the  propellor. 

Uy  proposed  method  of  propelling  submarines  is  a  rather 
revolutionaryrone,  but  every  factor  involved  has  been  tried  out 
separately,  in  an  experimental  way,  and  after  a  reasonable  amount 
of  actual  trying,  there  is  no  doubt  in  my  mind  that  it  will  enable 
our  Government  to  build  submarines  which  will  have  50#  greater  speed 
than  is  possible  with  the  present  known  methods.  V 


Thomas  A.  Edison,  Esq., 


7/5/16 


After  the  proper  Committee  has  carefully  gone  into  what 
I  propose,  I  will  he  glad  to  appear  before  them,  and  try  to  answer 
any  questions  which  may  occur  to  them. 

Yours  very  truly.

Dear  Sir: 

In  reply  to  yours  of  the  fifth  instant, 
let  me  suggest  that  you  had  hotter  try  the  experi¬ 
ment  in  a  small  way.  You  may  get  incomplete  com¬ 
bustion,  leakage ,  etc.,  and  produce  no  ahsorhshle 
gases •  She  Davy  men  have  thrown  out  several  schemes 
where  very  slight  wakes  wore  shown.

Referring  to  (4)  and  (6):-  Keep  putting  facts  before  Senators. 


During  House  consideration  of  Fortification  Bill,  Dallingor  offered  amendment 
to  Tavenner  rider  making  it  inapplicable  in  any  department  if  a  majority  of 
workors  therein  stated  in' writing  they  wanted  bonus  and  time-study.  This  amend¬ 
ment  was  voted  down  by  Tavenner  and  associates,  showing  plainly  they  know  that 
the  workers  do  want  these  methods,  but;  are  not  to  bo  allowed  to  prove  it. 

During  Senate  consideration  of  this  bill,  Senator  Weeks  blundered  by  oaring 
his  amendment  to  strike  out  Tavenner  rider  before  any  discussion  was  had.  This 
opened  way  for  motion  of  Bryan  to  lay  on  table  (not  debatable)  the  Weeks  amend¬ 
ment  It  was  laid  on  table  by  voto  36  to  20,  39  not  voting.  (Record,  June  30, 


The  majority  leader  of  the  House  advised  us  that  a  letter  from  the  President 
indicating  his  opposition  to  tho  riders  would  be  sufficient  to  eliminate  them. 
This  was  conveyed  to  the  President  in  time  to  prevent  passage  of  the  rider  on 
the  first  bill  (Fortifications)  to  be  acted  on  in  the  House.  So  far  as  known, 
the  President  took  no  action,  Telegram  followed  by  letter  to  President  offer¬ 
ing  evidence  of  real  desire  of  workmen,  was  not  acknowledged.

Dear  Sir:- 


The  South  Baltimore  Harbor  and  Improvement  Company  of 
Anne  Arundel  County  is  the  owner  of  large  tracts  of  water  front 
at  Curtis  Bay,  Maryland,  and  I  deBire  to  submit  the  same  for  your 
consideration  in  connection  with  the  location  and  establishment 
of  the  Naval  laboratory,  provided  for  in  the  new  Naval  Appropri¬ 
ations  Bill  now  pending  in  Congress. 


I  especially  call  your  attention  to  the  proximity  of 
this  Company’s  property  to  the  large  industrial  plants,  that  are 
engaged  in  the  manufacture  of  chemicals  and  other  products  valu¬ 
able  to  the  nation  industrially  and  defensively.  Its. Railroad 

and  Shipping  facilities  are  unexcelled,  and  it  is  within  thirty 
minutes  ride  from  the  famous  Johns  Hopkins  Hospital  and  University. 
Furthermore,  a  large  number  of  Shipbuilding  Plants  are  located  in 
this  vicinity. 


Curtis  Bay  is  strategically  situated  in  Anne  Arundel 
County,  near  Baltimore,  Maryland,  and  the  United  States  Govern¬ 
ment  has  already  located  one  of  its  Revenue  Cutter  Stations  at 
this  place.  I  also  take  the  liberty  of  calling  your  attention 
to  a  report  made  in  1884  by  Ensign  W.  J.  Chambers,  U.  S.  N. , 
published  by  an  Act  of  Congress  and  submitted  to  the  Honorable 
Jos.  L.  Hawley  and  others,  a  Special  Committee  of  Congress,  in 
which  he  recommends  Curtis  Bay  for  the  location  of  a  great  Govern¬ 
ment  Navy  Yard,  speaking  of  it  as  one  of  the  finest  land-locked 
harbors  on  the  Atlantic  seaboard. 


We  would  be  pleased  to  give  you  whatever  information 
you  might  desire,  in  reference  to  this  proposition,  at  any  time.

I  desire  to  call  a  meeting  of  th<f  Haval  Consulting  Board'-"** 

1 _ ^  in  September  so  we  can  effect  an  organization  under  the  new 

law  and  make  provision  for  the  early  erection  of  the  Laboratory. 

I  think  this  meeting  ought  to  be  held  in  Washington,  so  that  we 
could  organize  it  here  and  then  subsequent  meetings  could  be  held 
wherever  you  think  best.  How  would  Wednesday.  September  ISth, 
suit  you?  If  that  is  agreeable,  if  you  will  please  have  your 
Secretary  to  telephone  me,  I  will  name  that  date.  If  that  date 
will  not  suit,  please  name  a  date  as  near  that  as  possible,  say

The  passage  of  the  Havy  Bill  oarrying  the  big  appropriation

i:  ^ 

The  Naval  Appropriation  Bill^will 


speoifio  provision  for  the  location  of  a  Bite  for  the  proposed  ^ 
Research  laboratory,  provided  in  the  measure,  when  it  is  passed 
finally,  the  Senate  having  receeded  from  its  amendment  oallingX  , 
for  the  erection  of  the  same  in  Washington.  \  r.  hv-<***  / 

The  absence  of  suoh  provision  will  leave  the 
question  in  the  hands  of  the  Navy  Bepartment,  which  will  be 
guided,  of  course,  by  the  Naval  Consulting  Board,  of  which  you 
are  the  eminent  ohairman.  For  this  reason  I  have  taken  the 
liberty  of  presenting  to  you  some  facts  in  regard  to  the  desira¬ 
bility,  due  to  natural  advantages,  of  having  this  laboratory 
erected  at  the  Philadelphia  Navy  Yard. 

The  Government  now  owns  at  the  Philadelphia 
Navy  Yard  a  vast  track  of  land  available  for  this  purpose, 
situated  on  a  deep  fresh  water  ohannel  into  which  the  largest 
battleships  afloat  or  contemplated  may  be  brought.  The  Phila¬ 
delphia  Navy  Yard  is  only  a  few  minutes  ride  from  the  centre  of 
Philadelphia,  and  enjoys  all  the'  transportation  facilities  both 
by  land  and  water  that  are  enjoyed  by  that  city.  Philadelphia 
is  acknowledged  by  Naval  authorities  to  be  the  best  labor  market 
in  the  East. 

These  advantages  which  I  have  endeavored  to 
enumerate  comprise  virtually  all  of  the  recommendations  made  by 
your  Board  in  its  first  report  on  the  question.  In  faot,  upon 
reading  the  report  and  knowing  the  natural  advantages  of  the 
Philadelphia  Navy  Yard  I  oould  but  think  that  the  Naval  Consult¬ 
ing  Board  had  that  port  in  mind  in  outlining  its  specifications 
for  an  ideal  site. 

It  is  my  honest  conviction  that  anything  you 
do  which  may  lead  to  the  ereotion  of  the  Research  laboratory  in 
Philadelphia  will  not  be  amiss,  but  will  be  for  the  best  interest 
of  all  concerned.  I  would  appreciate  it  if  you  would  let  me 
know  of  developments  in  this  matter. 

Very  truly  you^s,

My  dear  Mr.  Edison, 

Appreciating ^thT  fact  that  you 
are  much  interested  in  the  location  of  the  VM 
laboratory  to  he  used  for  the  investigation  and  re 
ear oh  in  all  matters  pertaining  to  Haval  dev8d°f" 

<mt,  I  am  taking  the  liberty  of  w£itd“S  ^  setting 
orth  reasons  why  the  laboratory  should  be  looated 
in  this  section. 

X  earnestly  hope  that  you  may 
find  an  opportunity  to  oome  dawn  and  1?°J.ove^At“? _ 
situation  before  you  make  any  recommendation  to  the 
Honorable  Secretary  of  the  Havy.  This  Sanitation 
will  he  at  your  services  for  any  further  information, 
or  to  Conduct  you  or  any  committee  you  may  desire  to 
send  to  investigate. 

My  reasons  for  suggesting  thiB 
locality  are  as  follows; 

1st .  This  looation,  on  aooount  of  the  mild¬ 
ness  of  the  winters,  offers  superior  advantages,' the 
waters  in  this  seotion  being  entirely  free  of  ice  and 
always  open  to  shipping. 

2md.  Beoause  it  is  near  to  Washington  and 
aooessible  at  all  times  to  the  capital 
Havy,  and  wohld  therefore  be  most  convenient  to  such 
officers  of  the  Havy  Department  as  might  find  it  neoes 
ear y° to 8 spend  par t  of  their  time  at  said  laboratory. 

3rd.  Beoause  in  this  immediate  vicinity  are 
looated  the  Horfolk  Havy  Yard  and  the 
nhin  building  plant,  where  vessels  are  likely  to  be 
always  in  the  course  of  construction,  and  there  would 
be  no  difficulty  in  procuring  skilled  labor  and  hav¬ 
ing  suoh  outside  work  done  as  may  be  required.

4th.  Because  mild  ana  salubrious  climate  of  this 
section  will  prove  conducive  to  Beeuring  the  1 best 
class  of  work  both  in-doors  and  out  aoorB  the  year 
around. 

5th.  .Beaouse  it  has  excellent  transportation  S 
facilities,  both  hy  land  and  water,  from  all  points 
of  the  country,  north,  west  and  south,  at  rates  which 
will  compare  with  any  seaport  looation. 

6th  The  ample  and  pleasant  hotel  accommodations, 
both  in  the  City  of  Horfolk,  and  at  Old  Poiflt  and New¬ 
port  Hews  would  tend  to  make  this  point  an  attractive 
looation  to  the  members  of  the  Haval  Advisory  Board 
who  would  be  interested  in  the  work  to  be  carried  for¬ 
ward  at  said  laboratory. 

7th.  Beaouse  a  laboratory  located  at  this  point 
would  be  protected  by  the  guns  of  Fortress  Monroe,  and 
the  construction  of  the  great  fort  at  Cape  Henry,  when 
completed  will  render  the  waters  in  these  parts  practi¬ 
cally  immune  from  attack. 

Hoping  that  you  will  give  thiB  looelity  favor¬ 
able  consideration  on  account  of  its  many  advantages, 

I  am

To-day  there'^calXe^.dh  me  a  Mr.  Samuel  Spitz  whose 
home  is  in  Oakland,  California,  #2646  -  14th  Avenue. 

Mr.  Spitz  tells  me  that  he  has  developed  a  device 
that  enables  him  to  see  through  dense  fog,  and  also  to  pierce  the 
darkness  of  the  night  and  to  clearly  Identify  and  distinguish 
objects  at  sea  up  to  five  miles  away  from  the  point  of  vision. 

He  tells  me  he  has  laid  this  matter  before  our 
Secretary  of  Navy,  Mr.  Daniels,  and  that  the  Naval  Board  is  about 
to  make  further  tests  at  the  Laboratory  in  Oakland. 

He  expressed  a  desire  to  have  the  honor  of  meeting 
y4u  and  as  X  am  on  several  Committees  identified  with  National 
Defense,  and  have  been  working  on  some  programs  for  our  own  govern¬ 
ment,  I  am  asking  the  liberty  of  giving  him  a  letter  addreBBed  to 
you. 

So  that  you  may  know  who  he  is ,  and  what  he  has  done , 
I  am  mailing  this  in  advance  of  his  call.

In  view  of  the  facV  that  the  defeat  of 

y>>-tXo 

Senate  amendment  to  the  Haval  Appropriation  Bill,  which  di-  < 
reoted  that  the  proposed  Naval  Experimental  laboratory  should 
be  erected  in  Washington,  onoe  more  leaves  the  selection  of  a 
site  for  this  Institution  an  open  question,  we  wish  to  reiter¬ 
ate  the  request  that  has  previously  been  made  by  the  Chamber  of 
Commerce  that  Philadelphia  should  be  selected  as  the  place  where 
this  Experimental  Station  should  beJ^Alt.^ 

To  successfully  oo^fJifi#ork  of  such  an  es¬ 
tablishment  it  is  necessary  that  it  be  located  at  a  point  which 
may  be  easily  reached  by  deep  dral^tt •yessels that  it  may  be 
near  the  source  of  supply  of  material,  tequired  and  close  to  a 

community  of  skilled  artisans  trained -l^lhe- various  branches 

of  meohanieal  and  ohemical  processes  involved  in  carrying  on  the 
work  of  such  a  laboratory. 

It  is  desirable  that  Buch  a  Station  should  be 
in  close  touch  with  the  shipbuilding  industry,  but  at  the  same 


Mr.  Thomas  A.  Edison.  TV/O. 

time  so  located  that  the  experimental  work  of  the  government 
oould  he  carried  on  with  absolute  seorecy. 

All  of  these  advantages  exist  at  Philadelphia, 
in  addition  to  which  the  approaoh  from  the  sea  could  he  so  pro¬ 
tected  as  to  make  it  practically  safe  from  attack  from  that 
direction. 

In  the  opinion  of  the  Philadelphia  Chamber  of 
Commerce  the  conditions  existing  at  this  city  should  he  given 
most  oareful  consideration  before  the  location  of  the  proposed 
Laboratory  is  decided  upon  and  that  it, would  be  to  the  best 
interest  of  the  entire  country  if  this  city  should  be  selected 
as  the  location  for  this  plant. 

We  therefore  respectfully  petition  that  when  the 
question  of  the  selection  of  a  site’ rf or  the  Laboratory  is  serious 
ly  considered  that  you  use  your  influence  toward  having  the  city 
of  Philadelphia  seleoted.

full  particulars  concerning  the  business  to  be  transacted  at  the  meeting 
of  the  Board  whioh  will  he  held  in  Washington  on  Tuesday  the  19th  Inst.  It 
is  expected,  however,  that  the  following  matters  will  be  discussed:- 

1.  Suoh  re-organisation  of  the  Haval  Consulting  Board  as  may  he 
called  for  hy  the  fact  that  the  Board  has  been  duly  legalized  hy  Act  of 
Congress  in  the  recent  Haval  Appropriation  Bill.  (See  attaohea  quotation  A 
from  said  Bill). 

S.  Discussion  of  plans  of  the  Experimental  laboratory  for  whioh 
the  sum  of  $2,000,000  has  been  appropriated  in  the  Aot  above  mentioned. 

(See  attaohea  quotation  B  from  said  Bill). 

3.  Consideration  of  the  various  sites  whioh  have  been  suggested  for 
the  laboratory. 

4.  Consideration  of  plan  whereby  the  need  of  the  Havy  *x  for  an 
increased  number  of  engineer  officers  both  active  ana  on  the  reserve  list 
may  be  brought  to  the  attention  of  the  civilian  engineers  of  the  United.

6.  Beports  of  Committees. 


Further  Information  concerning  the  meeting  is  contained  in  the 
following  note  Just  reoeived  from  Dr.  M.  R.  Hutohison,  who  haB  been  in 
telephone  oonmmnioa tion  with  Secretary  DanielB:- 

We  will  spend  three  days  on  this  next  trip.  We  go 
to  the  Secretary's  offioe  at  11  A.  M.  on  the  19th.  We  then  go 
aboard  the  Mayflower  for  lunch  and  to  hold  our  meeting.  While 
on  hoard  she  will  he  on  way  to  Southern  Drill  Grounds.  We 
spend  the  night  aboard  and  on  the  20th  witness  target  praotioe 
all  day  and  until  12  midnight.  Thursday  morning  we  arrive  in 
Washington  and  depart  for  our  respective  homes. 


Further  particulars  will  he  forwarded  aB  soon  as  they  are  received, 
and  it  should  he  noted  that  the  plan  for  the  proposed  trip  depends  mainly 
upon  the  weather  whioh  prevails  next  week,  as  Naval  target  praotioe  is  not 
attempted  in  had  weather  owing  to  the  faot  that  small  boats  must  he  used 
in  connection  with  the  work.

In  uursuance  of  authority  conferred  by  the  Act  of 
Congress' entitled  "An  Act  Makin"  appropriations  for  the 
naval  service  for  the  fiscal  year  ending  June  thirtieth, 
nineteen  hundred  and  seventeen,  and  for  other  purposes", 
approved  August  29,  1916,  a  board,  legally  designated 
the  "Haval  Consulting  Board",  is  hereby  constituted  and 
appointed  for  the  purpose  of  consulting  and  making  recom¬ 
mendation  to  the  Department  concerning  matters  affecting 
the  naval  establishment. 


The  members  of  such  Board  are,  as  you  are  aware,  not 
to  receive  any  salary  or  compensation,  their  services 
being  voluntary. 

Provision  is  made  by  the  law  for  the  expenses  in¬ 
curred  by  and  in  connection  with  the  Board, and  appropriate 
instructions  will  be  issued  to  the  Paymaster  General  of 
the  Havy  relative  to  the  defraying  of  such  expenses. 

The  Board  will  meet  at  the  Navy  Department,  Washington, 
on  Tuesday,  the  19th  instant,  for  the  purpose  of  organiza¬ 
tion,  and  will  meet  thereafter  when  convened  by  the  Depart¬ 
ment,  and  at  3uch  other  times  and  places  as  may  be  specified 
by  you.

'in  welcoming  the  members-  of  the  Naval 
Consulting  Board,  Secretary  Daniels 


’  In  the  creation  of  the  Naval  Sivil-iraw  Consulting  Board,  a 
new  experiment  has  been  tried  in  voluntary  patriotic  service 
for  the  country.  Your  presence  here  today,  with  the  imprimatur 
of  Congressional  action  upon  what  has  been  undertaken,  shows 
that  the  experiment  has  hehind  it  united  public  approval  and 
undivided  public  support. 

When  war  burst  upon  Europe,  it  was  evident  that  some  of 
the  great  nations,  while  ready  with  dreadnaughts  and  sea  craft, 
and  while  having  more  or  less  trained  officers  and  men,  lacked 
what  the  war  has  taught  us  is  essential,  to  wit,  the  utilize- 
tion  of  the  inventive,  engineering  and  scientific  talent,  and 
the  ability  to  readily  mobilize  the  industries  of  the  country 
for  national  defense.  Trained  men  were  called  from  munition 
plants  and  machine  shops  to  serve  in  the  trenches.  It  required 
reverses  to  teach  the  folly  of  putting  men  skilled  in  the  making 
of  shells  to  carrying  guns,  for  while  there  developed  a  shortage 
of  irioni  the'  fi'rtSt  crisis  came  when  men  lacked  the  munitions  to  wage 
an  effective  war..  These  men  were  soon  recalled  to  the  plants  and 
factories  where  they  did  more  for  their  country's  defense  in  molding 
the  instruments  of  war  than  they  could  render  on  the  field  of  battle. 
The  United  States  has  now  put  in  operation  a  policy  that  regards  men 
making  munitions  as  enlisted  for  national  defense  as  truly  as  the 


-2- 

men  wlio  follow  the  colors  in  the  shock  of  actual  oonfliot.  ; Never 
again  will  any  country  fail  to  appreciate  tuat  the  mechanic  an . 
the  munition  maker  is  the  man  behinc.  che  gan.  ■ 

But  we  learned  lessons  from  twis  great  war  unicU 
trying  through  the  Baval'  Consulting  Boaru  to  make  available,  -..e 
fi?s?Bwas  the  need  of- cooperation,  study,  and  research  between 
civilian  and  naval  experts,  engineers,  and  scientists.  Uot  a 
few  of  the  inventions  that  have  been  most  valuable,  in 
vpio-unent  came  from  the  brains  of  civilians.  -<pen  it  seemet.

longing  to  the  War  Department  or  some  other  department  of^the^ 
Government  could  be  obtained  without  Congressional  action.  N

MEMORANDUM. 

Should  the  President  authorize  the  use  of  land  under  the 
control  of  the  War  Department  for  the  Naval  Experimental  and 
Research  Laboratory  which  he  has,  without  doubt,  authority  to 
do,  as  advised  the  day  before  yesterday,  it  is  recommended  that 
no  executive  order  be  issued  transferring  such  land  from  the 
War  Department  to  the  control  of  the  Secretary  of  the  Navy,  as 
the  Attorney  General  holds  that  the  President  is  without  au¬ 
thority  to  transfer  the  control  of  land  owned  by  the  Government 
from  the  control  of  one  Department  to  that  of  another. 

The  occupation  by  the  Naval  Experimental  and  Research 
Laboratory  of • a  site  within  a  military  reservation  would  be, 
as  expressed  by  the  Attorney  General,  "at  the  sufference 
only"  of  the  War  Department  and  action  by  Congress  would  be 
necessary  to  the  permanent  transfer  of  the  land  to  the  Navy 
Department.

/Dear  Sir;  v  f&- 

About  a  year  ago  I  sent  you  a  letter  in 
reference  to  a  site  on  Staten  Island  for  the  ex¬ 
perimental  laboratory  of  the  Naval  Advisory  Board. 

I  enclose  a  copy  of  my  letter  of  that  date,  also 
another  blue  print  of  the  property,  colored  red. 

The  property  belongs  to  Thos.  Williams, Esq. ,  25th 
Street  and  11th  Avenue,  New  York  City. 


I  also  desire  to  call  your  attention  to^. 
a  plot  on  the  East  Hiver,  right  at  the  entrance  to 
Long  Island  Sound.  I  refer  to  Old  perry  Point,  or 
Zerega  Point,  Block  20,  Lot  1,  on  the  New  York  City 
Tax  Map.  This  property  contains  86  acres  of  upland 
and  28  acres  of  salt  marsh,  making  a  total  of  114 
acres.  There  is  a  large  stone  residence  on  the  proper 
ty,  rebuilt  about  ten  years  ago,  with  the  usual  out¬ 
buildings.  The  property  belongs  to  the  Estate  of 
Augustus  Zerega,  is  free  and  clear  of  mortgage,  and 
is  offered  for  sale.  A  proposition  would  be  con¬ 
sidered.  I  enclose  a  diagram  of  the  property.  There 
is  a  small  plot  of  five  and  one-half  acres  in  the  S.Xf. 
corner  of  the  property  which  belongs  to  another  estate 


and  can  probably  be  bought.

Mr.  Hudson  Maxim, 

Pear  Mr.  Maxim: 

There  is  a  jnovement  to  locate  the  experiment 
station  and  research  library  for  the  Navy,  for  the  establish¬ 
ment  of  Y/hich  Congress  made  recently  an  appropriation  of  a 
million  and  a  half,  at  or  near  the  U.  S.  Naval  Academy  at 
Annapolis,  Maryland,  where  there  is  already  an  experiment  sta¬ 
tion  on  a  modest  scale  and  where  I  am  persuaded  there  are  faci¬ 
lities  for-  carrying  on  this  work  which  are  not  apt  to  be  found 
elsewhere.  The  nearness  of  the  site  to  Washington,  its  defensi- 
bility,  the  buildings  and  grounds  already  available,  its  use¬ 
fulness  in  connection  with  the  Naval  Academy,  its  value  in  the 
training  of  officers  and  midshipmen  stationed  there,  are  all 
apparent.  I  hope  before  your  vote  is  given  on  this  important 
matter  you  will  carefully  consider  Annapolis. 

I  suppose,  of  course,  you  know  that  the  great  BATTLE 
CRY  OE  PEACH,  in  which  you  were  interested,  is  to  be  followed 
presently  by  THE  BATTLE  CRY  OP  WAR  in  which  I  am  interested. 

Yours  very  sincerely,

[ATTACHMENT/ENCLOSURE] 


Landing,  New  Jersey, 
October  3,  1916. 


My  dear  Dootor  Brady  J 


Your  letter  of  the  35th  ultimo  ia  received,  and  I 
appreciate  the  interest  you  are  taking  in  the  matter  of  the  looation  of 
the  laboratory  of  the  Naval  Consulting  Board.  I  will  btfing  your  let¬ 
ter  to  the  attention  of  the  Board. 

I  am  not  one  of  the  oommittee  appointed  for  the  looation  of 
the  site,  but  doubtless  at  the  proper  time  several  siteB  will  be  submitted 
by  the  Committee  to  the  entire  Board  for  consideration  and  ohoioe. 

There  are  so  many  needs  to  be  taken  into  oonsideration  in  the 
ohoioe  of  a  site  that  I  trust  you  will  not  be  impatient  with  me  if  I  do 
not  immediately  approve  of  Annapolis. 

Most  of  the  members  of  the  Naval  Consulting  Board  live  either  in 

the  vicinity  of  New  York  or  in  such  other  proximate  parts  of  the  oountry 
as  to  make  some  spot  near  New  York  preeminently  preferable,  unless  some 


other  site  not  too  far  from  New  York  may  prove  to  have  such  exceptional 
advantages  as  to  out-weigh  the  big  advantage  of  availability  which  New 
York  has. 

While  the  members  of  the  Board  may  be  endowed  with  so  muoh 
patriotism  as  to  believe  that .they  would  be  willing  to  devote  the  same 


time  and  attention  to  their  work  in  a  laboratory  looated  at  Annapolis 
as  they  would  if  it  were  looated  near  New  York,  still,  when  the  time 
comes,  they  will  find  their  home  and  business  ties  strong,  and  that  con¬ 
venience  and  oomfort  make  a  loud  appeal. 

The  private  businesses  of  most  of  the  members,  even  without  the 
added  duties  imposed  by  their  position  on  the  Naval  Consulting  Board,  are 
already  so  strenuous  and  exacting  as  to  take  their  whole  strength  and  to 
occupy  their  waking  hours  end  even  intrude  on  sleep.  Therefore,  I  con¬ 
ceive  the  convenience  of  get-at-ableness  for  the  members  of  the  Board  to 

be  the  ohief  desideratum.  _  .  ..  . 

Regardlese  of  all  that  has  been  said  in  the  press  about  the  de- 

,urtUlW  of  loontlns  U»«w  “I=  fI“

weight.  This  country  at  the  present  time  is  as  vulnerable  as  a  Jelly¬ 
fish,  and  there  is  no  spot  in  it  which  would  oause  any  of  the  great 
military  powers  muoh  inoonvenienoe  to  reaoh.  Chicago,  St.  Louis, 
Cinoinnati  are  essentially  as  unprotected  and  as  unsafe  as  any  of  our 
coast  towns,  if  war  should  find  us  unprepared.  Those  oities  would,  in 
the  event  of  invasion,  share  their  portion  6f  the  blast  and  the  burden, 
and  would  bleed  with  Boston  and  San  Franoisoo. 

This  oountry  must  have  a  navy  adequate  to  its  needs,  and  its 
needs  are  absolute  seourity  for  the  lives  and  property  of  its  citizens 
in  every  part  of  it. 

The  appointment  of  the  Naval  Consulting  Board  was  a  measure 
for  national  defense.  The  work  of  the  Board  will  be  to  help  prepare 
the  oountry  to  proteot  itself,  and  the  main  use  of  the  laboratory  will 
therefore  be  to  make  the  nation  strong  where  it  is  now  weak  by  the  em¬ 
ployment  of  new  inventions  and  devices  for  the  equipment  of  the  oountry 
against  war,  and  in  the  organisation  find  standardization  of  the  nation's 
industries  for  quick  mobilization  for  efficient  duty  in  the  event  of 
war.  Therefore,  anything  which  will  tend  to  lessen  the  amount  of  suoh 
work  on  the  part  of  the  Board  will  prove  a  far  greater  disadvantage 
than  the  disadvantage  of  being  looated  at  any  point  on  the  Atlantio 
seaboard  now  unprotected  against  attaok. 

The  laboratory  will  not  at  any  time  be  likely  to  have  muoh  in 
it  whioh  would  oripple  the  oountry  if  destroyed  or  which  might  serve 

the  enemy  very  greatly  if  captured,  because  whatever  the  laboratory 
may  turn  out  will  likely  be  duplicated  and  utilized,  and  in  the  event 

of  war  being  deolared  against  us  whatever  there  might  be  in  the  labors 
tory  could  quickly  be  removed,  and  anything  that  could  not  be  removed 
could  be  destroyed  without  bery  great  sacrifice. 

It  seems  to  me  that  if  one  were  to  sit  down  with  a  pair  of 
oompaeses  and  draw  a  circle  around  New  York  a  hundred  miles  in  radius, 
he  would  surely  include  an  area  within  whioh  the  laboratory  should 
certainly  be  located.  The  laboratory  should  be  looated  on  some  body 
-2- 


[ATTACHMENT/ENCLOSURE] 


of  water  deep  enough  and  broad  enough  for  neoeeeary  experiments  with 
submarines,  even  ae  large  ones  as  are  now  contemplated,  and  there 
Should  be  sea  room  enough  for  racing  and  maneuvering  with  high-speed 
motor  boats.  Also,  there  ehould  be  a  suitable  gun-range  for  testing 
guns  of  moderate  oaliber. 

The  site  should,  furthermore,  include  a  sufficiently  large 
land  area,  besides  water  area,  for  practice  flights  and  experiments 
in  reconnaissance  and  attack  with  aeroplanes. 

I  appreciate  fully  the  advantages  of  being  located  near  some 
Navy  Yard,  and  also  the  advantages  of  Annapolis  as  a  location  if  it 
were  net  for  the  fact  that  it  is  so  distant  and  difficult  of  access.

of  politicians .  The  work  of  the  Naval  Consulting  Board  must  be 
pure  of  politios,  or  itB  work  will  not  be  pure.  The  praotioal 
politician  (add  praotioal  means  much  when  applied  to  politios)  is 
a  nemesis  of  evil  eye  and  slanderous  tongue  that  defames  xkish 
what  it  mentions  and  blights  whatever  noble  thing  it  lookB  upon. 

Yes,  I  have  learned  that  The  Battle  Cry  of  Peaoe  is  to 
be  followed  by  a  great  motion  picture.  The  Battle  Cry  of  Vfar,  of 
which  you  are  the  author.  I  understand,  also,  that  it  is  a  very 
great  piece  of  work.  You  deserve  big  credit.

10  SHE  COiaim'iiE  Oil  SUES  :•  .  ,  .  - 

’  '  I. have  personally  examined ' 

both  sides  of  tho  Hudson  up  as  far1  as  Tarrytown,  and 
find  nothing  suitable  for  the  laboratory.  On 'account 
of  the  Ice,  I -did  not  go  beyond  Tarrytown. 

I  have  also  examinod  Governors  island. 

Ehero  is  plenty  of  space  here  and  it  is  a  vox-y  desir¬ 
able  location  for  only  one  thing  and  that  is  the  Quick¬ 
ness  of  obtaining  supplies  which  is  imperative  and  of 
enormous' advantage  to  a  laboratory,  there  tho  nature 
of  the  work  constantly  changes  and  the  materials  re¬ 
quired  arc  of  such  a  diverse"  charac ter.  On  the  other 
hand,  experiments  with  the  thro o  most  important  de¬ 
vices  needed  by  the  liavy  would  -be  hampered  and  .almost 
impossible  at  Governors  island,  to  wit,  heavy  Hydro¬ 
planes  -.  Submarines  and  the  various  dovicos  for  obtain¬ 
ing  information  on  land  from  points  far  out  to  sea. 

•  V  .She  Harbor  is  very  .crowded  with  boats,  and 

real  sea  conditions  cannot  ho  had  nor  aro  there  any  - 
facilities  for  experimenting  With  information  dovicos. 

Governors  Island  doos  not  seem  to,  be  utilised 
by  the  Government.  The  Port ,  is  of  no  value;  the  acre¬ 
age  is  204-1/2;  and  the  water  is  3b  feet  at  the  dock. 

I  have  also 'visited  fort  Vladsworth.  the 
acreage  here  is  226;  the  water  on  about  half  the  front¬ 
age  is  44  feet  deep  within. fifty-feet  of  the  shore.  - 
the  water  shoals  rapidly  ,  on  oi-storly  half . 

. Ihoro  would  be  ample  room  hero  at  the  eastern 
end  and  on  the  high  hill,  but  it  would'  be  somewhat  un¬ 
handy  and  has  the  samo  objections  as  the  KuAbou  and  Gov¬ 
ernors  Island  Sites.-  '  , 

I 'have- also  visited  Atlantic  Highland  region 
and  .Sandy  Hook. 

All  the  conditions  roquirod  wo  find  at  tho 
Hook  -  rough  and  quiot  watoie  on  tho  two  sidos, twonty- 
foot  or.moio  at  tho  old  Railroad  Hock  whero  stoamors 
for  J{ew,  York  departed  -  now  abandonod.  Tho  Govornmont 


Pago  flo.  2  —  So  tho  Committee  on  Sites. 


has  a  Railway  running  full  length  of  tho  Hook.'  only 
the  oxtroma  ond  is  occupied  by  Port  and  Proving  Ground. 
There  are  1300  acres  and  the  laboratory  could  easily 
got  100  to  150  acres  and  have  tho  uso  of  much  moro  for 
special  experiments,  -  this  being  tho  best. part,  ana 
without  disturbing  anything  now  in  uso  or  contemplated. 
ShQ-0  are'  covoral  villages  near,  with  two  street  car 
linos  and  the  How  Jorsey  Central,  thero  would  bo  ample 
housing  capacity  for  the  employees. 

Should  this  place/  be  decided  upon,  I  would 
suggest  wo  obtain  about  ono-h'nif  .acre  on  tho  apex  of 
"  the  IJavos  ink  Mountain  for  experiments  with  procuring 
far-tosca  information.  This  would  be  an  ideal  spot' 
for  such  experiments,  as  night  and  day  there  are  so 
many  largo  ships  .approaching  this  point.  There  is 
ample  room  for  smooth  and  rough  water  experiments  with 
Hjyd^'Ojr^lanos^aj^^ubmarinas ,  without  much  interference. 

X  noticed  at  one  or  two  placed,  gravel  which 
could  bo  crushed' and  graded  sice  of  sand  for  concrote 
work. 

iiith  a  small  and  fast  motor  boat,  trips  to 
Hew  York  can  be  made  to. and  from  in  one  hour.  The 
Hew  Jersey  Central's  time  is  Railroad  to  nave Dime,  two 
hours,  Hoot  to  Atlantic  .Highlands  and  train  to  iiavesink 
one -hour  and  thirty-minutes. 

I.  would  recommend  the  Committee  to  visit  Ft. 
V.adsv.orth  and  to  make  a  rather  more  "extended  investiga¬ 
tion  of  Sandy  Hook. 

X  do  not  toko  seriously  the  cry  about  putting 
the  laboratory  at  some  spot  not  reached  by  tho  cnemys 
guns.  This  argumont  is  good  for  a  munitions  factory, 
but  the.  laboratory  is  suite  diffor'ont.  Wo  should  not 
sacrifice  idoalsd  conditions  for  obtaining  ouiclt  and  prac¬ 
tical  results  for  some  futuro  contingency  which  may  not 
occur  for  years. 

'  In  caso  the  laboratory  was  destroyed,  t ben  it 

would  become  greater  than  ever  for  tho.  aon  could  bo 
moved  and  every  maohino  and  othor  shop  in  the  Country 
would  and  could  bo  utilisod.  , 

I  am  oollocting  more  data  in  regard  to  Sandy  Hook, 
and  will  forward  it  lator. 


Yours  truly,

Dear  Sir: 

I  auly  received  your  very  full  ana  interesting  report 
ooncerning  Sandy  Hook  as  a  possible  location  for  the  Naval  laboratory. 

I  have  made  full  copies  of  your  report  ana  have  sent  them  to  all  the 
members  of  the  oommittee. 

Kessrs.  Addicks,  Sprague,  Baekeland,  Whitney  and  myBelf

Annapolis,  ana  the  report  of  this  trip  1b  now  being  prepared  ana  will 
be  sent  you  within  a  few  days. 

I  note  that  your  investigation  of  Hudson  River  sites  did  not 
go  north  of  Tarrytown  on  aooount  of  the  possibilities  of  navigation 
being  impeded  by  ioe.  I  therefore  think  you  will  be  interested  to 
hear  that  regular  shipments  by  water  are  made  by  the  Rockland  lake 
quarries,  which  are  some  ten  miles  north  of  Tarrytown  ana  within  a  mile 
of  Groton  Point,  whioh  haB  been  aiggestea  as  a  possible  site.  X  have 
askea  the  owners  of  the  Croton  Point  property  to  send  you  full 
information  concerning  it,  ana  to  repeat  to  you  in. writing  their

Mr.  Edisc 


to  mo,  but  I  think  wo  ought  to  do  something  to  determine 
the  probable  work  of  the  laboratory,  and  that  we  ought 
also  to  visit  the  7,'ashington  and  Sandy  Hook  sites,  before 
m8king  n  decision. 

Captain  Kberle  was  probably  right  when  he  said 
that  if  the  laboratory  was  to  be  a  large  manufooturing 
plant,  Annapolis  was  not  the  place  for  it,  while  if  it 
was  to  be  a  plnoe  for  research  into  the  or obi erne  of  the 
Uavy,  he  thought  Annapolis  wbb  the  right  looation.  This 
ia  my  feeling  today,  but  the  main  point  is  to  determine 
about  what  work  will  be  undertaken  and  continued  in  the 
laboratory.  It  is  almost  impossible  for  mo  to  be  un¬ 
prejudiced  in  trying  to  learn  the  best  typo  of  laboratory. 
I  was  carried  away  by  the  words  of  Hr.  Edison  and  by  Mb 


brood  viow,  but  X  keop  Rotting  book  to  the  idea  that 
the  building  of  o  submarine  was  an  unfortunate  illus- 
trntion  of  the  typo  of  work  to  be  done.  Thie  exper¬ 
iment  is  probably  under  way  in  our  ship-building  navy 
yards,  and  ought  to  proceed  faBter  there  then  it  would 
be  likely  to  os  a  port  of  the  wo rk.  of  o  laboratory 
built  for  a  million  dollars.  The  problems  which  hove 
been  suggested  to  us,  including  those  of  Admirr.1  Mel¬ 
ville,  ought  to  indicate  the  desired  field  of  work,  and 
these  make  me  favor  Annapolis.  I  cm  impressed  with  the 
importance  of  dose  connection  between  the  present  Havel 
engineering  laboratory  ana  the  Haval  Academy  post-graduate 
work . 

iJhile  the  admirals  who  supplied  us  with  prob¬ 
lems  ought  to  know  more  about  their  needs  and  the  appli¬ 
cability  of  the  laboratory  to  them  than  we  civilians, 
still  we  do  not  need  to  hesitate  to  propose  «  new  plans 
exceeding  their  modest  hopes,  if  we  see  how  onoh  plans 
can  be  made  good-  This.  I  assume,  is  lir.  Edison's  view. 

Admiral  Melville  had  the  needs  of  the  H»vy 
hotter  outlined  in  1903  than  they  have  been  outlined 
slnoe,  and  the  plan  he  proposed,  of  putting  the  exper¬ 
imental  laboratory  at  Annapolis,  was  carried  out.  That 


3 


plan.  If  it  hnd  been  properly  booked  financially , 
would  have  put  our  Kavy  where  it  wsnto  to  be.  In 
other  wordc,  the  present  experiment  station. is  the 
outcome  of  our  government's  ntteropt  to  solve  the  same 
problems  we  arc  now  working  on.  X  believe  the  lib¬ 
eral  enlargement  of  that  work  conforms  most  nearly  to 
what  the  Envy  wonts-  The  problems  Seoretery  Ticniolo 
lately  proposed  ere  of  the  norae  type  us  those  origi¬ 
nally  suggested  by  “lielville ,  and  vould  mostly  fit  the 
laboratory  at  Annapolis  if  it  were  enlarged. 

V/hcn  I  learned  that  only  about  320,000.  c 
year  is  devotFOui^jbecf.rcb  work  at  Annapolis,  I  was 
ecrprised/V^lj,‘i!.i3^t.^ W  exceedingly  able  presentation 
of  the  nde&jCfr  S££vV*Uw  Wnd  the  building  of  the  plunt 
at  Annapo|l^i'^hr.tl^^6ljlogethor  57CO,COO.),  only  J-20.00C. 
a  year  is  now^ expend^;  we  certainly  make  a  mistake  in 
storting  an  entirely* separate  line  of  work  with  only  one 
million  dollorp  appro priut ion.  It  would  bo  fnr  bettor 
to  add  to  the  good,  but  poorly  supported  start  elrenay 
made  at  Annapolis.  This  is  espeoiolly  true  when  we  see 
that  more  lend  is  available  there  and  that  the  character 
of  the  men  already  interested  is  first-olaBS.

In  Re:-  Ejperimental  and  Research  Laboratory. 


Dear  Sir:- 

I  note  that  yon  are  interested  in  looating  a  £ite  for 
the  construction  for  the  above  laboratory.  I  have  a  plaoY  located 
at  the  south  point  of  Daufuskie  Island  South  Carolina  which  would  y-eJOn\y 
-he-  to  answer  all  the  requirements  you  desire  which  I  can  offer  you 
for  the  site  of  this  laboratory.  The  entire  place  contains  five  hun- 
dres  acres,  about,  and  is  located  on  the  south  east  point  of  Dau— 
fuskie  Island  in  South  Carolina  which  is  eighteen  miles  from  Savan¬ 
nah,  Georgia  down  the  Savannah  River.  It  is  four  miles  across  the 
sound  from  Tybee  Island,  Georgia. 

This  place  has  a  frontage  of  about  a  half  mile  on  Cal- 
ibogue  Sound  and  also  a  frontage  on  the  river  at  the  side.  There 
is  deep  water  in  the  river  up  to  the  side  of  this  plaoe.  There  is 
a  large  old  fashioned  house  in  good  condition  on  this  point.  Two 
artersian  wells.  The  Island  is  touched  by  two  steamboat  lines  ply¬ 
ing  between  Savannah  and  Beaufort,  S.  0.  and  Savannah  and  Bluff ton 
S.  C.  There  is  no  ice  ever  forms  in  this  climate  and  in  other  re¬ 
spects  the  oharaoter  of  the  looation  seems  to  me  to  oomply  with 
your  requirements.  In  the  event  the  entire  five  hundred  acres  is 
not  desired,  I  will  be  willing  to  sell  such  portion  as  you  would 
desire  and  at  a  very  reaaonable  figure.  Ifyou  af® 
the  extent  to  desiring  further  informt4oirT£»d  will  advise  me,  i 
shall  be  pleased  to  give  you  any  informajidn  in  my  power  in  ref-

Thomas  A.  Edison,  Esq-,

Dear  Mr.  Edison: 

I  understand  that  we  are  expected  to  make  an 
early  decision  in  the  matter  of  the  laboratory  site..  If  you 
have  not  yet  made  your  contemplated  trip  to  Annapolis  I  want 
to  urgethat  you  withhold  final  judgement  until  you  have  seen 
what  they  have  there-  I  not  only  have  in  mind  that  you  will 
be  surprised  at  what  they  have  to  show  in  the  way  of  present 
equipment  but  that  if  you  do  not  go  and  another  site  should 
then  be  selected  the  local  people  will  be  much  offended  and 
we  shall  be  criticized  accordingly. 

Annapolis  is  the  only  place  where  the  locality 
itself  has  shown  any  pergonal  interest  in  getting  this  laboratory 
and  they  have  put  up  quite  a  little  money  in  literature  and  enter¬ 
tainment.  I  know  they  are  looking  forward  to  your  projected 
visit  and  this  causes  me  to  write  you  this  line.

NO. 


United  States  Navy  Yard, 

NEW  YORK.  N.Y. 


Hovember  22,  1916. 


My  dear  Fir.  Edison: 

At  the  suggestion  of  Mr.  Hutch\ 
to  give  you.  my  opinion  as  to  the  poini 
in  the  selection  of  “  “JJ“  J>‘“  J'1'“ 


I  am  writing 

_  _  to  he  considered 

site  for  the  Naval  Laboratory. 


I  think  that  the  laboratory  should  be,  in  a  way, 
a  connecting  link  between  the  Navy  (which  is  the  fleet 
and  its  officers)  and  the  manufacturing  and  scientific 
talent  of  the  country,  which  is  represented  by  your 
Board;  our  needs  and  troubles,  which  we  have  difficulty 
in  solving  for  ourselves,  to  be  presented  to  the  laboratory 
which  thereupon  attempts  the  solution  both  by  experiment 
in  the  laboratory  and  by  calling  upon  the  members  of  the 
Board  for  their  technical  opinions  and  suggestions. 

If  this  be  the  purpose  of  the  laboratory,  it  should 
be  in  a  location  where  its  communication  with  both  these 
groups  would  be  most  convenient  and  expeditious. 

Both  the  Navy  Department  and  Naval  Academy  are  apart 
from  the  fleet,  their  functions  being  quite  different  from 
the  solution  of  problems  of  materiel.  The  technical  Bureaus 
of  the  Department  do,  in  a  way,  have  to  do  with  the  solution 
of  materiel  questions  but  only  through  the  medium  of  corre¬ 
spondence  and  are  never  in  actual  touch  with  the  work,  ihe 
Navy  Yards,  on  the  contrary,  are  in  actual  physical  touch 
with  the  fleet  and  its  officers  and  the  troubles  and  needs 
of  the  fleet  are  brought  to  the  yards.  It  would  seem  there¬ 
fore  that  the  laboratory  should  be  as  near  as  possible  to  a 
large  yard  where  all  classes  of  ships  come  frequently  so 
that  the  laboratory  force  may  see  by  direct  examination  of 
materiel  and  conversation  with  the  officers  all  the  points 
of  the  problems  to  be  considered. 


The  New  York  yard  receives  and  repairs  all  classes  of 
ships,  especially  the  latest  ships,  and  there  are  always  ships 
of  all  classes  at  this  yard.  It  has  the  largest  force  of  offi¬ 
cers  on  duty  there  and  the  largest  and  most  complete  equipment 
of  shops  and  tools  of  any  yard.  It  has  for  a  long  time  received 
and  tested  all  eleotrical  equipment  purchased  for  the  Navy  and 
plans  and  develops  much  of  the  new  appliances  installed  on 
ships,  notably  in  radio  installations.  It  has  by  far  the 
largest  force  of  workmen,  many  of  whom  are  trained  along 


definite  lines  of  naval  work,  and  the  services  of  these 

min  can  he  calls!  upon,  if  the  laboratory  is  near  the  yard, 

either  for  work  in  the  yard  shops  or  in  the  laboratory  it 
self,  should  occasion  arise. 

On  the  other  hand,  the  members  of  the  Consulting 
Board  are  mostly  in  or  around  Hew  York  and  this  neighborhood 
is  full  of  manufacturing  concerns  of  ®Jerir  ^tn^  ^latch  ean 
he  and  frequently  are  called  upon  by  the  yard  for  consults, 
tion  in  regard  to  the  needs  of  the  ships.  Even  a  business 
concern  that  has  its  works  at  a  distance  penally  maintains 
an  agency  in  Hew  York  from  which  can  be  obtained  all  needed 
information. 

The  stock  of  material  maintained  in  Hew  York  is 
probably  greater  than  in  any  other  place  in  the  country  so 
that  the  laboratory,  if  located  here,  is  in  bhe  closest 
proximity  to  the  fleet,  its  officers,  the  Board, 

the  engineering  interests  of  the  country,  and  the  supply  of 
engineering  materials. 

The  Haval  Academy  is  not  in  any  way  similar  to  the 
laboratory.  It  takes  boys  and  gives  them  a  foundation  of 
scientific  knowledge  upon  vAiieh  they  may  become  officers  of 
ability  after  they  have  had  sufficient  experience  with  the 
fleet  Its  purpose  and  atmosphere  are  academic  rather  than 
practical,  while  the  laboratory  should  be  intensely  Poetical. 
Probably  Schopenhauer  could  evolve  a  system  J ^ 

as  well  or  better  when  immured  in  the  backwoods  but  it  is  not 
so  with  the  work  of  the  laboratory,  -  that  needs  to  be  in  the 
aotive  center  of  engineering  progress. 

The  practical  man  does  not  usually  write  about  the 
things  that  he  does  and  even  if  they  do  get  into  books,  the 
information  is  several  years  behind  the  times  ' l^arv  t^see4' 
To  really  find  out  what  is  going  on,  it  is  necessary  to  see 
and  talk  with  the  men  who  are  doing  things.  When  I  have  had 
occasion  to  go  to  the  technical  libraries  for  help,  I  have 
very  seldom  found  it,  the  books  were  full  of  generalities 
but  nothing  definite.  They  say  that  when  a  steam  cylinder 
is  v/orn  “barrel  shaped  it  should  he  rehored,  which  I  knew, 
but  as  to  how  much  it  may  be  worn  without  the  necessity  of 
reboring,  the  books  are  silent.  The  only  way  to  know  things 
is  to  be  among  them,  not  to  read  about  them. 


For  the  above,  and  other  reasons,  it  seems  so  obvious 
to  me  that  Hew  York  is  the  most  favorable  site  for  the  labora¬ 
tory  that  I  am  impatient  in  talking  about  it  or  in  listening 
to  the  oratorical  efforts  of  those  who  display  more  energy 
and  ability  in  talking  than  in  thinking. 


As  to  the  location  of  the  site  in  the  vicinity  of 
Hew  York,  it  must  he  easy  of  access  to  the  laboratory 
enrolovees,  to  the  supply  houses,  and  to  the  Havy  Yard, 
and,  if  possible,  on  land  already  owned  by  the  Government 
Fort  Hamilton  reservation  seems  to  meet  all  these  require 
ments  pretty  well  but  there  may  be  other  objections  to 
this  site  that  I  am  not  acquainted  with. 


With  great  respect  and  regard,  X  am, 
Sincerely  yours ,

Very  respectfully. 


Deo  ember  2,  1916, 


My  dear  Mr.  Hutchison 

During  my  conversation  with  MT.  Edison 
at  the  time  of  his  recent  visit  to  the  Philadelphia  Navy 
Yard  he  mentioned  to  me  a  method  of  greatly  intensifying  the 
sound  of  the  flute  or  violin  somewhat  as  follows: 

£■'{- 

The  aaat  was  sound  at  the  large  end  of  a  very 
attenuated  oone  or  megaphone  mouthpiece.  The  smaller  end 
of  this  attenuated  cone  was  in  turn  oonneoted  with  the  smaller 
end  of  another  long,  small. angled  oone. 

I  am  wondering  whether  it /would. hey  possible 
for  you  to  get  for  me  a  sketoh  and  the  asfify  data  on 

this  point.  What  I  am  aiming  at  is  to  he  able  to  apply  this 
to  the  voice  tube  systems  aboard  ship  and  if  possible  to  . 
make  the  voice  tube  piping  not  larger  than  one  inoh  internal 
diameter . 


individual  while  speaking  is  oust omari U 
greater  than  two  or  two  and  one-half  inches  in  diojueter, 
there  does  not  appear  to  me  to  be  any  advantage  gained  in 
making  a  mouthpiece  greater  than  a  two  and  one-half  inoh 
oirole . 


If  the  experience  of  Mr.  Edison  oan  be  applied 
to  this  question  the  problem  then  resolves  itself  to  -  what 
inoluded  angle  iB- the  suitable  one  to  adopt  to  attach  a  two 
and  one-half  inoh  mouthpieoe  to  the  one  inoh  voioe  tube  with 
a  corresponding  expanding  megaphone  or  mouthpiece  at  the 
further  end,  i.e.  -  receiving  end  ef  the  tub*

Copied  from  Hydrographic  Bulletin,  Ho.  1289.  Published  by  the 
Hydrographic  Office,  Havy  Department,  Wash.  D.C. ,  May  13,  1914. 

li-rom  report  of  Captain  J.H.  Quinan,  U.S.H.C.  MIAMI,  on  Ice  Patrol, 
April  15  to  May  1,  1914. 

"Although  there  was  no  wind,  there  was  a  heavy  westerly  ground 
swell  caused  by  a  previous  blow,  and  when  we  reached  the  largest  berg 
we  found  by  observation  and  distance  run  by  log  that  we  had  drifted 
eastward  during  the  night  22  miles.  We  stopped  near  the  largest  berg 
and  by  range  finder  and  sextant  computed  it  to  be  450  feet  long  and 
130  feet  high.  Although  we  had  gotten  within  150  yards  of  the 
perpendicular  face  of  this  berg  and  obtained  no  echo  from  the  steam 
whistle.  Prof.  Fessenden  and  Mr.  Blake,  representatives  of  the  Submarine 
Signal  Co.,  obtained  satisfactory  results  with  the  submarine  electric 
oscillator  placed  10  feet  below  surface,  getting  distinct  echoes  from 
the  berg  at  various  distances,  from  one-half  mile  to  2  1-2  miles. 

These  echoes  were  not  only  heard  through  the  receivers  of  the  oscillator 
in  the  wireless  room,  but  v/ere  plainly  heard  by  the  officers  in  the 
wardroom  and  engine  room  storeroom  below  the  water  line.  Sound  is  said 
to  travel  at  the  rate  of  4,400  feet  per  second  under  water.  (Hote  by 
Hydrographic  Office.-  The  Smithsonian  Physical  Tables,  5th  revised 
edition,  do  not  agree  with  this  datum. )  The  distance  of  the  ship,  as 
shown  by  the  echoes  with  stop  watch,  corresponded  with  the  distance 
of  the  ship  as  determined  by  range  finder.  On  account  of  the  great 
velocity  of  sound  through  water,  it  was  our  intention  to  try  the 
oscillator  at  a  greater  distance  for  even  better  results,  but  a  thick 
snow  storm  drove  us  in  to  shelter  on  the  Banks  again. 

On  the  26th,  I  allowed  the  vessel  to  drift  with  moderate  northerly 
wind. 

On  the  morning  of  April  27,  anchored  in  31  fathoms  of  water  with 
75  fathoms  of  chain  in  order  to  make  current  observations.  We  found 
the  current  to  be  tidal,  but  very  weak,  running  HUE.  in  the  forenoon 
and  SSW.  in  the  afternoon.  This  data,  however,  was  very  unsatisfactory, 
for  when  we  determined  the  ship's  position  by  observation  we  found 
that  we  had  drifted  to  the  southward  and  westward  about  53  miles  in 
36  hours.  Prof.  Fessenden  also  took  advantage  of  the  smooth  sea  to 
further  experiment  with  his  oscillator  in  determining  by  echo  the  depth 
of  water;  the  result  giving  36  fathoms,  which  seemed  to  me  very  close. 
That  evening  a  HUE.  gale  sprang  up  and  continued  all  next  day  with  fog, 
rain,  hail,  and  snow. "

PROPOSED  REPORT 
of 

OOMMITTEE  OH  SITES 


In  arriving  at  a  conclusion  aa  to  which  site  on  the 
whole  presents  the  greater  advantagea  under  existing  oonditiona 
it  is  eaaential  to  consider, firBt,  the  funotlonB  of  the 
laboratory  and,  second,  the  manner  in  which  it  must  be 
operated. 

The  original  oonoeption  was  for  a  laboratory 
costing  $5,000,000,  in  whioh  not  only  researoh  work  but 
rapid  heavy  construction  of  all  kinds  could  be  oarried  on; 
but  despite  all  efforts  the  total  for  construction  and 
operation  was  out  to  $1,500,000,  of  which  only  $1,000,000 
has  actually  been  authorized;  and  this  at  a  tine  of 
increases  of  from  25  to  100  per  cent  in  costs  of  labor  and 
materials. 

Beaause  of  thiB  great  and  regrettable  reduction  in 
the  appropriation  and  the  seriouB  limitations  resulting 
therefrom,  it  is  vital  that,  to  make  the  most  of  the  available 
funds,  there  should  be  no  unnecessary  duplication  in  the 
laboratory  of  equipment  and  facilities  which  already  exist 
in  other  Government  plants,  and  no  avoidable  expenditures 
outside  of  buildings  and  equipment. 

For  instance,  we  must  give  up  the  idea  of  con¬ 
struction  of  large  guns,  or  vessels  of  any  type,  or  the 
manufacture  along  commercial  lines  of  large  numbers  of 
any  kind  of  equipment.  All  heavy  work  must  be,  and  can 


[ATTACHMENT/ENCLOSURE] 


Page  3  - 

better  be  built  at  other  points,  and  only  comparatively  light 
work  based  upon  research  and  experiment  should  be  carried  on  at 
the  laboratory. 

As  to  the  manner  in  which  it  should  be  operated, 
the  idea  that  the  work  should  be  more  or  less  under  the 
direotion  of  Bureau  Chiefs,  individually  or  oolleotively,  or 
the  members  of  the  Naval  Consulting  Board,  must  be  discarded, 
for  suoh  would  lead  to  a  many-headed  and  inefficient  organiza¬ 
tion. 

Instead,  the  laboratory  should  be  under  a  responsible 
officer  of  high  rank,  to  whom  the  various  Bureau  Chiefs  should 
turn  over  their  problems,  accompanied  by  all  available 
information.  And  so  too  with  regard  to  problems  which  may  oome 
up  before  the  Consulting  Board. 

It  will  undoubtedly  be  necessary  to  frequently 
oall  upon  the  Bureaus  for  advioe  and  information,  but  it  will 
not  be ‘necessary  for  the  Chiefs  to  visit  the  laboratory  except 
on  rare  oooasions.  This  faot,  while  making  reasonable  access 
from  Washington  desirable,  removes  the  necessity  of  the 
laboratory  being  immediately  under  the  shadow  of  the  Navy 
Department.  Moreover,  a  large  part  of  the  work  will  consist 
of  purely  soientifio  researoh  and  experiment,  which  will 
require  a  reasonable  amount  of  isolation  and  freedom  from 
interference  and  oritioism. 

With  the  foregoing  general  oonoepts,  consideration 
of  various  sites  was  taken  up,  with  specific  referenoe  to  a 
number  of  characteristics,  each  more  or  less  influential  in 
arriving  at  a  decision.

Page  3  - 

Of  the  nearly  fifty  whioh  have  been  formally 
presented,  on  public  and  private  lands,  from  New  Hampshire 
to  Louisiana  and  all  east  of  the  Mississippi  River,  but  few 
oould  be  considered  favorably;  in  any  event,  before  investigating 
privately  owned  lands,  it  was  necessary  to  ascertain  whether 
there  was  available  land  dixeotly  controlled  by  the  Navy 
Department,  or  transferable  with  more  or  less  delay  from  the 
War  Department,  whioh  could  meet  the  necessary  requirements. 

With  these  considerations  in  view,  members  of  the 
Committee  have  made  a  detailed  investigation  of  a  number  of 
localities  in  and  about  New  York,  and  also  of  the  League  Island 
Navy  Yard  at  Philadelphia,  the  site  of  the  present  experimental 
station  at  Annapolis  and  the  Belleville  Magazine  site  at 
Washington. 

Eaoh  of  the  above  places  possesses  a  number  of  the 
requirements  whioh  are  deemed  essential,-  none  of  course 
possesses  them  all. 

CONCLUSIONS; 

Careful  consideration  of  the  whole  subject  indicates 
as  the  best  selection  the  site  on  whioh  the  present  experimental 
station  at  Annapolis,  now  under  the  Bureau  of  Steam  Engineering, 
is  situated;  and  that  this  station  be  removed  from  Bureau  oontrol 
and  consolidated  with  the  proposed  Researoh  Laboratory  and 
Experimental  Station,  under  the  direction  of  a  naval  offioer 
distinguished  by  his  scientific  attainments  and  managerial 
oapaoity,  who  should  ordinarily  report  direotly,  so  far  as  is 
practicable,  to  the  Navy  Department. 


[ATTACHMENT/ENCLOSURE] 


The  special  characteristics  noted  are  as  follows: 

(1)  Location,  ownership  and  available  area. 

Both  of  land  and  water. 

Across  the  Severn,  forming  part  of  the 
grounds  under  the  general  jurisdiction 
of  the  Superintendent  of  the  Naval 
Acadeny;  nearly  100  aores  out  of  a 
total  of  about  300,  are  available; 
ample  water  front, 

(2)  Character  of  land  and  purchase  cost. 

Or  the  cost  of  changing  contour? 

No  purchase  cost  and  but  low  cost  of 
ohanging  contour,  even  with  extensive 
building  operations;  land  offers  ex¬ 
cellent  foundations. 

(3)  Water  front,  depth  of  water  and  proximity 

Of  Navigable  Channel. 

Ample  frontage,  with  a  fine  masonry 
dock  already  constructed,  a  29  ft. 
channel,  and  room  within  three  miles 
to  anchor  the  entire  Atlantic  fleet. 

(4)  fi)iarant,flT  of  bottoms  and  stability  of  channel. 

Easily  dredged,  if  required,  and  with 
practically  no  shifting  changes  in 
ohannel. 

(5)  Amount  of  dredging  if  necessary,. 

And  likelihood  of  ice. 

Depends  upon  how  large  a  ship  is  desired 
to  bring  close  to  the  laboratory,  but  it 
would  seem  that  accessibility  of  a 
dreadnaught  to  the  dook  is  unnecessary; 
there  is  but  little  ice  formation. 

(6)  Range  of  tide  and  character  of  water,. 

Whether  fresh,  brackish  or  salt.. 

Low  tidal  ohange,  water  dean  and  dear  from 
sewerage,  and  brackish.

Good  for  all  year  work,  and  better  in

(8) 


mia.Tftnt.gr  ef  neighborhood,  considered  from 
'A  residential  standpoint. 


In  the  main  excellent,  and  near  enough 
to  Washington  for  reasonable  additional 
Booial  diversions. 


(9)  Character  of  Labor  Market. 

While  not  a  manufacturing  center,  and 
henoe  not  available  for  quickly  changing 
demands  for  meohanios,  such  would  form 
but  a  moderate  proportion  of  the  people 
employed,  many  of  whom  would  be  civilian 
scientists,  naval  officers  and  possibly 
men  from  the  enlisted  forces  who  have 
developed  special  aptitude. 


About  100  men  are  already  employed,  some 
of  whom  actually  live  in. Baltimore;  but 
it  is  a  trite  saying  that  labor  follows 
the  market,  and  if  there  should  be  here 
established  a  larger  and  more  important 
experimental  station  of  the  kind  now 
authorized  employing,  not  spasmodically 
and  erratioally  but  steadily,  skilled  men, 
many  would,  eventually  malce  Annapolis 
their  home.  There  would  he  lesB  likeli¬ 
hood  of  labor  union  troubles  than  elsewhere. 


(10) 


Karket  for  materials, 


Ordinary  operation  does  not  require  a 
hand-to-mouth  condition  calling  for  daily 
dependence  upon  the  jobbers  of a  great 
oity.  Of  the  manufacturing  establish¬ 
ments  throughout  the  country  large  numbers 
are  remotely  situated  from,  and  are  inde¬ 
pendent  of,  New  York,  and  there  is  no  good 
reason  why  with  proper  management  the 
proposed  laboratory  should  not  be  well 
enough  stocked  to  be  similarly  independent . 


Baltimore  is  within  50  minutes  by  trolley  and 
34  miles  by  water,  and  materials  can  be 
delivered  every  day  of  the  year.

for  example,  than  the  residential  part  of 
New  York  would  he  from  Bandy  Hook. 


Sentiment  of  Naval  Offioera. 

The  sentiment  of  most  of  those  of  wide 
experience  seems  to  he  strongly  in  favor 
of  either  Annapolis  or  Washington,  while 
some  who  have  not  seen  Annapolis  in  a  soore 
of  years  prefer  New  York.  Where  a  difference 
of  opinion  does  exist,  it  seems  to  largely 
he  founded  upon  the  assumption  that  the 
laboratory  is  to  he  an  annex  to  the  various 
Bureau  and  largely  under  their  direction, 

„  which  point  of  view  seems  incorrect. 

Where  a  preference  for  New  York  has  been 
voiced,  it  has  been  invariably  accompanied 
by  the  opinion  that  the  location  should 
be  on  the  main- land,  easily  aooessible  to 
either  Manhattan  or  Brooklyn.  There  is  no 
such  land  available. 


Secrecy  of  Operation  and  Safety  from  Enemy  assault. 

Admirably  situated  to  be  free  from  ordinary 
interference  and  unauthorized  visits  and 
offers  muoh  easier  supervision  of  employes. 

It  is  reasonably  free  from  enemy  attacks 
and  easily  defended  if  necessary  by  a  fleet. 


Oonoentration  of  Experimental  Work  and  Research, 

The  present  experimental  station,  in 
operation  for  some  years,  represents  a  direct 
investment  of  about  a  half  million  dollars, 
and  the  existing  facilities  and  equipment 
could  not  now  be  duplicated  for  less  than  an 
additional  quarter  of  a  million.  About  half  . 
a  million  dollars  has  been  expended  in 
oarrying  on  important  investigation  and  tests, 
now  requiring  the  work  of  100  men. 

This  constitutes  a  good  beginning,  and  if 
there  be  now  added  to  it  such  extensions 
in  buildings,  equipment  and  operation  as  are 
possible  by  the  proper  expenditure  of  the 
million  dollars  now  available  and  are  in  view, 
as  well  as  suoh  as  are  ordinarily  available 
for  the  present  station,  there  will  be 
established  a  dignified  and  effective  e^uip- 
ment,  more  impressive  in  results  and  oosting 
less  to  operate  than  two  separate  experimental 
stations  of  like  total  expenditure. 


[ATTACHMENT/ENCLOSURE] 


In  fact,  a  considerably  more  extensive 
equipment  oan  be  Insured  by  extending 
the  present  station  than  by  the  oonstruo- 
tion  of  an  independent  one,-  it  oan  be 
more  quickly  begun  and  put  in  operating 
condition,  and  important  experimental 
work  would  not  need  to  await  the  comple¬ 
tion  of  the  whole. 

Besides  the  provisional  plans  outlined 
sometime  ago  by  the  Chairman  other  plans 
showing  how  the  present  plant  oan  be 
extended  have  been  outlined,  and  as  soon 
as  an  agreement  on  general  features  is 
arrived  at  work  oan  be  instantly  begun. 

( 18 )  Congressional  Support. 

It  is  vitally  important  to  avoid  those 
sectional  influences  which  often  times 
interfere  with  Administration  and 
especially  Congressional  support, 
instances  of  which  are  tpo  numerous  to 
need  speoifio  mention.  At  Annapolis 
as  at  Washington,  the  laboratory  would 
be  on  national  territory  and  oan  be 
developed  along  national  lines,  in 
oonneotion  with  an  institution  in  whioh 
every  Member  of  Congress  has  an  individual 
interest,  and  whioh  oan  be  more  readily 
visited  by  him  than  any  other  place  under 
consideration  exoept  Washington. 

There  are  some  additional  important  considerations 
whioh  must  enter  into  any  broad  view  of  this  matter,  and  whioh 
should  oarry  weight  if  this  laboratory  is  to  be  developed  along 
possible  and  desirable  lines. 

Annapolis  is  the  Beat  of  the  United  States  Naval 
Academy,  the  prime  source  of  the  professional  education  of  the 
officers  who  are  especially  oonoerned.  It  shares  with  Washington 
the  individuality  of  national  distinction.  At  the  Academy  itself 
the  Government  has  within  recent  years  expended  in  superb 
housing  and  educational  buildings,  and  electrical  and  maohine 
equipment,  considerably  over  *10, 000, 000,  and  this  is  being 


[ATTACHMENT/ENCLOSURE] 


constantly  augmented.  In  addition  to  the  educational  facilities 
now  extended  to  naval  officers  at  Columbia,  Harvard  and  elsewhere, 
there  is  here  established  a  Post  Graduate  course  which  It  is 
hoped  may  be  extended  so  as  to  ultimately  make  less  necessary 
the  utilizing  of  other  University  facilities. 

The  graduates  of  the  Aoademy,  all  of  whom  must 
in  every  way  be  trained  in  the  praotioal  as  well  t*e  the 
theoretical  side  of  their  profession,  in  laboratory  and  machine 
shop  as  well  as  in  the  field  or  on  the  water,  comprise  many 
men  of  epeoial  fitness  for  scientific  research  to  whom  the'

scene  of  their  activities. 

This  laboratory  is  primarily  designed  to  be  for  the 
benefit  of  the  servioe  for  which  these  men  are  being  trained, 
not  for  the  benefit  of  civilian  scientists.  It  must  deal  with 
the  peculiarly  individual  problems  of  an. organization  concerning

My  dear  Mr.  Edison;- 

'  I  greatly  appreciate  the  fact  that 

you  have  so  soon  been  able  to  give  me  some  of  your 
valuable  time  in  connection  with  the  voloe  pipe  wort 
in  whioh  X  am  Interested.  I  know  that  I  shall  find  the 
suggestions  contained  In  your  letter  of  December  5th 
most  valuable. 

I  purpose  keeping  In  touoh  with  you 
through  your  advisory  engineer,  Mr.  Hutohison,  with  whom 
I  shall  correspond  more  or  less  frequently  on  this  subjeot, 
until  I  feel  that  we  have  thrashed  this  matter  out.

I  am  glad  that  you  for|esawJa|nd.V.were  able  to  stall  the 
objections  toJ§aMy\  Hook/Jn  account  of  tele  disturbing 
j^bffect  from  the  blast  of  the  big  guns  fir^i  there. 

]  There  is  no  one  thing  about  ^ich  there  is 

^greater  popular  error  than  respecting  tne'^mage  capable 
of  being  done  by  explosive  blasts  exerted  through  the 
atmosphere  at  even  short  distances.  The  actual  effect 
is  far  less  than  is  generally  supposed. 

Time  is  a  very  important  factor  in  the  doing 
of  damage  at  distances, with  explosive  materials.  While 
the  sound  of  an  explosion  may  be  heard  at  a  long  dis¬ 
tance  and  glass  be  broken  as  far  away  as  the  sound  can 
be  heard,  still,  the  very  brief  duration  of  the  pulsa¬ 
tion,  and  its  lack  of  massiveness  at  any  considerable 
distance,  renders  its  actual  disturbing  effect  small. 

A  propos  of  this,  and  in  support  of  the  truth 
of  what  you  said  yesterday,  let  me  call  your  attention

Dear  Hr.  Snow: 

I-  havo.  rocolvcd  .your  favor  of  tho 
8th  instant.  Since  ray  laat  letter  to  you  I  have 
thought  of  another  suggestion,  and  that  ic,  in 
your  experiments  I  would  try  brass  tubing  with  a 
glass  tube  inside.  Tho  Corning  Glass  Co.,  Corn¬ 
ing,  ,Ii.y.,  now  make  a  now  kina  "of  glass  which  would 
be  bo  good  for  this  purpope .  Wo  use  this  glues 
ourselves  for  primary  battery  jars.  While  the 
jars  arc  a  foot  square  ana  the  walls  of  one-auartor 
inch  glass,  wo  cap  pour  boiling  water  into  them 
without  any  crocking. 

I .  think  the  Corning  Gloss  Co .  can  moko 
the  tubes  In  twelvei  foot  lengths.  This  would 
reduce  your  friction  to  tho  limit  of  possibility 
-if  you  use,  say,  two-inch  iron  pipo  and  fairly 
closely-fitting  brass  glass  pipe  having  ono-oight 
inch  wall.  •  Youy  floxiblos,  if  used,  would  oauso 
you.a  .lot  of  loss. 

If- you  consider  an  inch-tube- system,  with 
a  Central  station,  using  small  leather  buckets  like 
thoso  used,  in  some  tologrnph  offices,  you  con  write 
tho  message,  pat  it  in,  ,  close  the  volvo  and  shoot  it 
to  Central,  and -Central  condo  it  to  tho  point  wanted, 
where  it  drops  out  automatically  and  rings  a  bell  or 
drops  a  signal1.  Compressed  air  is  used.  This  system 
would  be  quite  simple,  but  I  have  no  idoa  as  to 
whether  or  not  it  is  practical  for  your  purposo. 

•  Jf  wo  only  had  tho  llaval  Experimental  Lub or¬ 
atory  *  wo  could  make  anything  you  wanted  in  a  Bpace 
of  timo  that  a  huc'tlor  would  call  a  rocord. 

Yours  very  truly.

My  dear  Edison: 

I  am  enclosing  copy  of  majority  report  of  the 
Committee  on  Sites,  amended  to  include  the  arguments  for 
and  against  Sandy  Hook  as  required  hy  resolution  adopting 
the  report  in  favor  of  Annapolis.  The  amendment  expresses 
the  understanding  of  the  rest  of  us. 

In  forwarding  the  resolution  it  will  of  course 
he  necessary  to  send  a  copy  of  the  report  giving  the  reasons 
for  the  selection;  if  not  sent  it  would  he  called  for. 

I  am  in  hopes  that  after  you  have  gone  over  this 
you  will  see  your  way  to  make  tlie  report  in  favor  of  Annapolis 
unanimous,  since  the  hoard  as  well  as  the  Committee  are  so 
largely  in  favor  of  it,-  this  of  course  without  suppressing 
in  any  manner  your  views  as  given  in  the  report. 

In  such  case  the  report  will  he  slightly  amended, 
simply  to  say  that  on  final  consideration  you  would  join  with 
the  rest  of  us  in  recommending  Annapolis,  or  of  course  that  could 
he  done  hy  separate  letter. 


OF  THU  VHHGD  STATUS 


The  Department  is  pressing  for  a  conclusion^., 
and  it  is  desirable  that  the  notioe  of  the  decision  should 
go  forward  not  later  than  tomorrow,  Thursday. 


Very  truly  yours.

Thomas  A.  Edison,  Esq., 
West  Orange,  N.  J. 

Dear  Mr.  Edison: 


AMPERE, N.J..U.S.A. 

Deoember  14,  1916. 


You  spoke  to  me  yesterdayof  the  desirability 
of  running  the  turbines  at  very  high  speed,  mentioning  a 
periptejal  speed  of  15,000  feet  per  minute  for  the  generator, 
and  X  gathered  the  impression  that  you  meant  that  very  high 
speed  oould  not  be  availed  of  on  account  of  gear  limitations 
unless  electric  drive  was  used. 

Whon  running  at  the  highest  peripheral.  apood.  "Jhe 
shaft  speed,  of  oourse,  depends  upon  the  diameter  used  in  the 
design  of  the  turbine.  The  large  types  of  turbines,  are  of 
rather  large  diameter,  and  X  understand'  attain  perii>4k^Speede 
considerably  greater  than  you  mentioned.  I  e£r&e  'understand 
that  large  turbines  are  run  at  speedB  of  from  1500  to  3500 
RPM,  and  also  that  single  reduction  gears  in  ratio  of  7  to  1, 

8  to  1,  10  to  1  and  even  30  to  l,are  common  practice,  and  that 
olofts  have  been  run  up  to  30,000  and  40,000  H.P.  for  one  gear. 
The  propeller  speed  for  the  Battle  Cruisers  in  question  is 
350  R.P.M. 


It  seems  to  me  if  the  above  data  is  all  oorrect 
-thatit  has  been  quite  fully  demonstrated  that  it  is  entirely 
praotioal  to  get  the  advantage  of  the  great  simplicity  of  the 
single  reduction  geared  drive  in  the  Battle  Cruisers  in  whioh 
propeller  shafts  take  45,000  H.P.  each.  What  do  you  think? 


I  have  your  telephone  message  about  the  reversing. 
It  is  oommon  practice  all  over  to  reverse  by  turning  the  steam 
through  a  separate  set  of  reversing  buokets. 


I  enclose  a  list  of  a  lot  of  9hips  that  use  geared 
drive,  and  all  of  which  reverse  in  the  above  mentioned  way.  The 
British  Navy  is  building  a  lot  of.  high  power  ships  with  geared 
drive  in  which  very  great  power  i3  transmitted.  But,  as  you 
know,  they  will  not  let  out  any  of  the  definite  data.

REPORT 

of 

COMMITTEE  OH  SITES. 


In  arriving  at  a  conclusion  ao  to  ahioh  aits  on 
the  whole  prescnto  the  greater  advantages  under  exi sting 
conditions,  it  is  essential  to  oonaider,  first  the 
authority  for  and  functions  of  the  naval  laboratory,  and, 
second,  the  manner  in  which  it  suet  be  operated. 

The  Act  caking  appropriations  for  the  Haval  Scrvioe 
for  the  fiscal  year  ending  June  20,  1917,  provided  as  follows: 

EXPERIMENTAL  AMD  RESEARCH  LABORATOHT:  For  laboratory 
and  research  work  on  the  subject  of  gun  erosion,  torpedo 
motive  power,  the  gyroscope,  submarine  guns,  proteotion 
against  submarine,  torpedo  and  mine  attack,  improvement 
in  submarine  attachment a,  improvement  and  development 
in  submarine  engines,  storage  batteries  and  propulsion, 
aeroplanea  and  nlroraft,  improvement  in  radio  insta-llntlone, 
and  such  other  neoeossury  work  for  the  benefit  of  the 
Government  service,  including  the  construction,  equipment 
and  operation  of  a  laboratory,  the  employment  of  eoiontlfio 
civilian  assistants  as  may  become  nooeaaary,  to  be 
expended  upon  the  direction  of  the  Seoreta ry  of  the  Ra-vy 
(limit  of  coot  not  to  exceed  Sl,5C0,C00),  §1,000,000: 
Provided,  That  nothing  herein  shall  he  construed  aa  pre¬ 
venting  or  Interfering  with  the  continuation  or  under¬ 
taking  of  neoesnary  experimental  work  during  the  fiscal 
year  ending  June  thirtieth,  nineteen  hundred  and  seventeen, 
us  heretofore  conducted  under  other  appropriations: 

Provided  further.  That  the  Secretary  of  the  Havy  shall 
sake  detailed  reports  to  the  Congress  not  later  than 
June  thirtieth,  nineteen  hundred  and  seventeen,  and 
annually  thereafter,  shoving  the  manner  in  which  all 
expenditures  hereunder  have  been  made. 

The  original  conception  vas  for  a  laboratory 
involving  an  outlay  of  almost  #3,090, GOO,  in  which  not  only 


[ATTACHMENT/ENCLOSURE] 


Page  2  - 

research  and  wiriNMl  *ork  tat  heavy  contraction  of  .11 
kinds  could  be  rapidly  carried  on;  but  after  full  hearing 
the  K*val  Coaeittooo  the  total  proposed  for  construction 
and  operation  .a.  cut  to  8l.500.0C0,  of  *hlch  only  §1.000.000 
has  actually  boon  authorised;  and  this  at  a  tine  of  increase* 
of  from  25  to  IOC  per  cent  in  ooete  of  labor  and  materials. 

The  tense  of  the  Act  make  even  this  appropriation  cover 
not  only  oonatruotion  and  equipment  but  all  operating 
expenses  until  further  provision. 

Because  of  this  great  and  in  many  respects 
regrettable  reduction  in  the  appropriation,  and  the  serious 
limitations  resulting  therefrom,  it  is  vital  that  in  order 
to  cake  the  most  of  the  available  funds  there  should  be  no 
unnecessary  duplication  of  equipment  and  facilities  »hich 
already  exist  in  other  Government  plants,  and  no  avoidable 
expenditures  outside  of  buildings  and  equipment. 

For  instance,  land  and  vater  approach  costs  oust 
be  minimised,  and  the  idea  of  construction  of  large  guns, 
or  vessels  of  any  type,  or  the  manufacture  along  commerolu! 
lines  of  large  numbers  of  any  kind  of  equipment  must  be 
abandoned.  All  heavy  «ork  must  be  and  should  be  built,  and 
undoubtedly  can  be  better  built,  at  other  places,  and  only 
comparatively  light  *ork  based  upon  research  and  experiment 
should  be  carried  on  at  the  laboratory. 

As  to  the  manner  in  which  it  should  be  operated, 
the  idea  that  the  »ork  should  be  more  or  less  under  the 
direction  of  Bureau  Chiefs,  individually  or  collectively,  or 
the  members  of  the  Koval  Consulting  Board,  should  be  discarded.

for  snob  would  lead  to  a  m»ny-heaaed  and  Inefficient 
organisation. 

The  laboratory  should  bo  under  a.  responsible 
ofi'loer  of  high  rank  who,  because  of  his  ability  and 
personality,  would  constructively  co-operate  with  the  bureau 
chiefs,  and  thus  keep  in  closest  contact  with  the  growing 
needs  of  the  Havy.  On  the  other  band,  through  the  intimate 
help  of  the  Consulting  Board,  he  should  be  enabled  to  take 
rapid  and  radical  steps,  unencumbered  by  those  difficulties 
which  are  naturally  connected  aith  systematic  naval  eork. 

A  policy  should  be  pursued  which  will  demonstrate  to  the 
bureau  chiefs  that  the  laboratory  will  meet  their  needs 
without  demanding  their  oonstant  supervision.  It  is  hoped 
that  the  co-operation  will  be  each  that  nuval  needs  not  yet 
apprehended  will  be  foreseen  and  provided  for.  It  is  intended 
tht>t  new  apparatus,  whether  made  by  the  laboratory  or  elsewhere, 
should  be  thoroughly  tested  by  the  laboratory. 

The  experimental  work  already  carried  on  in  a  small 
way  by  the  Bureau  of  Steal*  Engineering  at  Annapolis,  and  by 
the  Bureau  of  Construction  at  Washington,  la  of  the  neoeasary 
type.  But  their  facilities  are  entirely  inadequate  for  modern 
requirements.  Such  problems  as  proposed  in  the  Act  of  Appro¬ 
priation  oan  only  he  attacked  by  more  extensive  equipment,  and 
solved  by  more  liberal  appropriation  than  the  bureaus  possess. 
With  increasing  complexity  of  naval  appliances,  the  burden 
of  conception,  as  well  a®  development  of  new  apparatus,  will 
have  to  be  assumed  by  the  S^vy,  and  facilities  should 
correspond  at  least  to  the  experimental  laboratories  now

In  aooord  with  the  foregoing  general  concepts,

reference  to  a  number  of  characteristics  each  * ore  or  leoo

Of  the  nearly  sixty  cites  which  have  been 
formally  presented,  on  public  and  private  lands,  £ xom  Hew 
K^spahire  to  Louisiana  and  all  east  of  the  Hisslsaippl  River, 
but  few  oould  toe  considered  favorably:  in  any  event,  before 
investigating  the  cerita  of  privately  owned  Undo  it  was 
necessary  to  ascertain  whether  there  was  available  governaent- 
owned  land  direotly  controlled  or  acquirable  by  the  Huvy 
Department  which  would  oee^f"  the  neoeaoory  requirements. 

The  members  of  the  Committee  have,  therefore, 

Bade  detailed  investigations  of  a  number  of  localities  in 
and  about  Sew  York,  the  League  Island  Jfavy  Tard  at  Philadelphia, 
the  site  of  the  present  experimental  station  at  Annapolis 
and  tho  Bslleview  H^g'tsine  site  at  tfashingten. 

Eaoh  of  the  above  places  possesses  a  number  of 
the  requirement*  which  aro  deemed  essential,-  none  of  course 
posseesoo  them  all. 

Broadly  speaking,  the  decision  as  to  site 
finally  narrowed  down  to  a  selection  in  the  vicinity  of  the 
national  Capitol  or  Sew  Tort,  the  Chairman  preferring  the 
latter  and  the  remaining  five  Reirbern  of  the  Cowalttee  being 
unanimously  in  favor  of  the  former.

The  difference  of  opinion  la  based  upon  eoaewhat 
different  conceptions  of  the  funotione  of  the  experiment 
station  and  laboratory  and  especially  of  the  relation  of 
the  Havjr  to  It. 

The  Chnirttan'e  point  of  view  may  be  expressed 
briefly  as  follows:  That  Sandy  Hook  has  ample  ground  available, 
and  although  an  Army  reservation  probably  can,  without 
unreasonable  delay,  be  transferred  to  the  Ba-vy  Department;  that 
it  has  water  on  both  aides  of  fair  depth;  that  it  is  within 
a  comparatively  short  distance  from  Men  York,  where  there  io  a 
large  market  for  materials  and  labor,  and  is  reasonably 
accessible  to  workmen  and  visit  by  members  of  the  ®-val  Consult¬ 
ing  Board.  He  feels  that  the  laboratory  should  be  essentially 
a  development  machine  shop  run  at  high  pressure  when  necessary, 
and  with  but  limited  research  f&cilltiea;  that  most  of  the 
baelo  facte  necessary  are  already  known;  and  that  ouoh  extra 
research  work  as  may  be  required  oan  be  o&rrled  on  at  ouoh 
places  as  the  Bureau  of  Standards,  Washington,  or  at  various 
private  experiment  til  research  laboratories  throughout  the 
country.  He  also  thinks  that  both  direction  and  operation 
should  be  essentially  civilian  end  largely  dlvoroed  from  naval 
influenoee  and  control,  while  with  regard  to  future  renuirecento 
he  believes  that  if  the  laboratory  makes  good  there  will  be  no 
difficulty  in  getting  all  the  soney  that  is  necessary. 

Disagreeing  with  these  opinions, the  remaining 
five  members  of  the  Committee  state  their  views,  first,  as 
to  Sandy  Hook,  and  second,  as  to  their  final  choice,  as 
follows:

The  speeding  of  work,  ao  far- an  the  handling  of  machine 
tools  and  men  are  concerned,  can  under  proper  regulations 
and  authority  be  aonduotod  in  one  place  as  cell  as  in  another. 

In  the  determination  of  locations  for  the  propoecd 
nitrate  and  armor  plate  plants,  freedom  from  attack  has  been 
given  due  Importance.  Sandy  Hook  la  subject  to  direct  naval 
attack  'it  long  range.  The  presence  of  the  proving  grounds, 
with  heavy  and  irregular  gun  fire,  is  objeotion.iDlc  and  the 
place  offers  poor  faoilltlco  for  aeroplane  or  other  outside 
touts  in  winter.

After  careful  consideration  of  the  whole  subject 
we  reo Oft send  an  the  beat  selection  the  site  on  which  the 
present  experimental  station  at  Annapolis,  now  under  the  Bureau 
of  Steam  Engineering,  is  situated;  also  that  this  station  be 
removed  from  the  Bureau  control  and  oor.oolidated  with  the  proposed

of  either  Annapolis  or  hishington,  while 
oona  who  have  not  seen  Annapolis  in  n  score 
of  years  prefer  Sew  York.  «l)ere  a  difference 
of  opinion  does  exist,  it  seems  to  largely 
be  founded  upon  the  assumption  that  the 
laboratory  lw  to  be  an  annex  to  the  various 
iuircnue  and  largely  under  their  direction, 
which  point  of  view  seems  incorrect. 

where  a  preference  for  Hew  York  has  seen 
voiced,  it  has  been  invariably  accompanied 
by  the  opinion  that  the  location  should  be 
on  the  «a in-land,  easily  accessible  to  either

The  present  experimental  station,  in

direct  investment  of  about  n  Half  mil¬ 
lion  dollars,  and  the  existing  facil¬ 
ities  and  equipment  could  not  now  bo

it  is  vitally  important  to  avoid  those 
sectional  influences  ar.ich  often  times 
interfere  with  Administration  and 
especially  Congressional  support, 
instances  of  which  are  too  numerous  to 
need  specific  mention.  At  Annapolis 
as  at  nehington,  the  laboratory  would 
be  on  national  territory  and  can  be 
developed  along  natiunul  lines,  in 
connection  with  an  institution  in  which 
every  hesu>er  of  Congress  hue  an  individual 
interest,  and  which  can  be  more  readily 
visited  by  him  than  any  other  place  under 
consideration  except  .;a  shins  tan. 

"here  are  some  additional  important  considera¬ 
tions  which  rant  enter  into  any  broad  view  of  this  matter,  and 
which  should  carry  weight  if  this  project  is  to  be  developed 
on  the  highest  and  moat  effective  plans. 

Annapolis  is  the  coat  of  the  United  States

or  THIS  UNITED  STATUS 

OF  I' I  CIS  OF  TUB  CHAIRMAN 

Okatsmje, "NAT.  December  lb,  1910. 

Hon.  Josephus  Daniels, 

Secretary  of  the  Navy, 

Washington,  D.  C. 

Sir:- 

I  do  not  agree  with  the  majority  of  the 
Committee 'on  the  selection  of  Annapolis  as  a 
site  for  the  proposed  Iiaval  Laboratory.  I 
believe  this  would  be  a  very  bad  selection  if 
rapidity  of  construction  is  to  be  a  dominating 
feature  of  the  Laboratory .  I  believe  the  best 
place  for  such  a  Laboratory  is  on  the  Sandy  Hook 
peninsula . 

2he  practical  advantages  of  Sandy  Hook 
are  as  follows: 

1.  Unlimited  amount  of  flat  land  away  from 
inhabited  places,  where  experiments  can  be  made 
unobserved. 

2.  Where  there  is  an  operating  proving  ground 
right  at  hand. 

S.  Where,  nearby,  there  is  a  highland  nearly 
300  feet  high,  invaluable  for  experimenting  on  cer¬ 
tain  strategic  devices. 

4.  Where,  on  account  of  the  narrow  strip  of 


Hon.  Josephus  Daniels .  -2-  12/lO/lC. 

land  projecting  into  the  sea,  certain  experiments 
and  tests  can  he  carried  out  under  more  nearly  prac¬ 
tice  conditions  than  at  any  other  point. 

5.  Chat  it  is  an  ideal  place  for  Aeroplane  work, 
v;ith  both  smooth  and  deep  sea  conditions,  in  view 
of  the  long  coast  and  beach  line  of  the  State. 

6.  Chat  it  gives  every  facility  for  experiments 
with  and  operation  of  Submarines. 

7.  Chat  no  ornamental  or  expensive  buildings  need 
be  constructed,  as  necessarily  there  will  be  no 
visitors  to  impress . 

0.  Chat  the  country  around  the  Havesink  Highlands 
is  the  finest  in  the  State  for  residence.  Monmouth 
County  is  the  richest  farming  County  in  Hev:  Jersey, 
and  living  is  cheaper  than  in  almost  any  other  part 
of  the  State. 

9.  Chat  there  is  ample  and  rapid  transportation  facil¬ 
ities  for  all  tho  men  likely  to  be  employed  in  the 
laboratory . 

10.  Chat  there  are  more  houses,  at  very  moderate  rents, 
procurable  in  the  IS  Cities  and  Eowns  adjacent  to  the 
Hook  than  at  any  other  point.  Hy  investigator  already 
reports  houses  for  over  COO  families  can  be  obtained  at 
very  moderate  rental  close  by  the  Hook  and  that  conditions 
in  that  respect  are  ideal. 

11.  Chat  the  laboratory  buyer  in  Hew  York  can  by  tele¬ 
phone  procure  and  ship  any  supplies  to  the  Hook  by  the 

small  Motor  Boat  owned  by  the  Laboratory  oweed-by . -fee 

L&boxttjioxy  quicker  than  at  any  other  site,  the  dis- 


Hon.  Josephus  Daniels, 


12/lb/lG. 


tance  being  1  hour  hy  this  boat  ana  2-l/2  hours 
by  Railway. 

12.  Shat  freight  from  two  Railways  can  be  taken 
right  to  the  laboratory  on  the  Government  Railroad 

at  the  Hook,  and  water-borne  freight  can  be  delivered 
at  the  Dock  of  the  laboratory. 

13.  In  ordinary  manufacturing  districts  employees 
arc  constantly  coming  and  going,  the  number  in  most 
cases  amounting  to  about  GO-;  of  the  turnover  of  all 
employed.  Sandy  Hook  region  not  being  a  manufacturing 
District,  I  think  the  men  employed  at  the  laboratory 
will  not  be  so  liable  to  change. 

14.  Hew  York  now  is,  I  believe,  the  largest  City 
in  the  World .  It  is  the  greatest  market  in  this 
Country.  In  Hew  York  nearly  every  article  sold  in 
the  United  States  can  be  found  in  stock.  In  the  City 
and  vicinity  of  Hew  York  is  the  greatest  collection 
of  factories  in  the  Country  making  the  most  diverse  artic 
les,  and  all  this  vast  variety  of  materials  can  be 
instantly  placed  at  the  disposal  of  the  laboratory. 

13.  A  majority  of  the  great  industries  of  the  Country 
have  a  Hew  York  office,  and  most  of  the  higher  officials 
reside  there.  To  these  men  we  can  appeal  for  small 
supplies  urgently  needed  at  once,  thus  eliminating  the 
usual  months  mill  delay, and  in  my  opinion  we  will  get 
them. 

16.  There  are  certain  strategic  devices  which  can 


Hon.  Josephus  Daniels, 


-4- 


12/1C/16. 


only  be  porfected  over  the  ocean  itself,  especially 
where  many  large  ocean  going  steamers  are  passing 
night  ancl  aay,  where  ha2e,  fogs  and  high  winds  often 
prevail,  and  these  necessary  conditions  are  found  at 
Sandy  Hook. 

17.  Che  Havy  will  be  certain  to  have  more  problems 
to  solve  than  those  set  forth  in  tho  Appropriation 
Bill,  and  it  may  also  be  expected  soon  that  Congress 
may  want  the  laboratory  to  construct  and  test  Army- 
devices  co-operatively  with  the  liavy. 

This  I  have  tuken  in  consideration  in  suggest¬ 
ing  Sandy  Hook. 

As  to  the  character  of  the  laboratory  itseli: 

I  recommend  that  it  be  one  that  is -constructed,  arranged 
and  run  as  a-  works  for  tho  rapid  construction  and  test 
of  experimental  machines  and  devices,  Chat  it  be  oper¬ 
ated  on  a  war  basis,  whore  speed  of  construction  is  the 
dominating  motto.  Chat  it  bo  operated  in  three  shifts 
of  8  full  hours  each.  Chat  every  machine  should  bo 
given  out  to  the  workmon  in  parts  one  man  to  a  part, 
to  the  end  that  when  tho  part  which  takes  the  longest 
time  to  make  is  finished,  the  whole  machine  is  finished. 
Chat  these  parts  are  spread  all  ovor  the  works  and  tnen 
brought  together  in  an  assembly  shop,  where  they  can 
be  put  together  by  trustworthy  men,  preserving  a  secrecy 
which  is  practically  impossible  in  the  usual  shop. 


Hon.  Josephus  Daniels,

I  do  not  think  that  scientific  research 
work  to  any  great  extent  will  he  necessary.  Kesearch 
work  in  every  branch  of  science,  and  industry,  cost¬ 
ing  countless  millions  of  dollars  and  the  labor  of 
multitudes  of  men  of  the  highest  minds  has  been  carried 
on  for  many  years.  -11  of  this  has  been  recorded,  and 
yet  only  a  rediculously  small  per  centage  has  as  yet 
been  applied  and  utilised.  It  is  therefore  useless 
to  go  on  piling  up  more  data  at  great  expense  and  de¬ 
lay  while  we  are  free  to  use  this  Ocean  of  facts. 

fhere  will  of  course  arise  many  things  tnat 
require  a  special  research.  Mach  of  this  can  oe  done 
at  the  proposed  laboratory,  but  in  certain  branches  of 
Ecience  U  would  be  better  to  use  the  facilities  and 
the  ilesearchers  at  the  other  Government  Bureaus  such 
as  the  Bureau  of  Standards,  3uroau  of  Chemistry,  and 
many  others, and  also  the  exceptionally  able  men  who 
are  the  heads  of  many  industrial  Kesearch  laboratories. 

I  do  not  fear  that  there  would  be  trouble  about  secrecy 
amo sing  the  latter. 

AS  to  the  management  of  the  proposed  laboratory. 
I  believe  it  should  be  civilian.  Also  that  the  civilian 
Secretary' of  the  U*r  should  control  through  an  appointed 
iiaval  Officer,  preferably  one  who  has  been  or  now  is  an 
industrial  manager,  of  a  llavy  Yard,  and  that  no  llnval 
Officers  who  have  their  own  duties  should  interfere  in 
any  way.  I  also  think  that  we/proceod  to  experiment  on 
the  special  devices  mentioned  in  the  appropriation,  as 


Hon.  Josephus  Daniels, 


-6- 


12/15/16. 


well  as  such  other  devices  as  the  ilavul  Officers 
sketch  out  and  pass  on  to  the  laboratory  through 
the  Secretary;  also  any  other  devices  suggested 
from  outside  sources  which  the  Secretary  of  the 
Uavy  thinks  should  be  made. 

In  concluding  this  report  I  want  to  suggest 
that  it  may  be  well  to  consider  the  erection  of 
temporary  buildings,  very  inexpensive  but  really 
as  good,  as  more  costly  ones,  and  which  would  lust 
for  many  years  and  be  fireproof.  At  any  time  the 
site  could  be  changed  or  permanent  buildings  erected 
and  any  mistake  of  judgement  could  be  corrected  at 
small  expense,  and  the  laboratory  would  quickly  be 
put  in  operation. 

I  expected  to  have  this  minority  report 
ready  to  be  forwarded  with  the  majority  report,  but 
I  was  busy  and  did  not  have  time  to  prepare  it  quickly 
enough. 

Hospectfully ,

thank  you  very  much  for  the  information 
concerning  the  glass  tubing,  and  also  am i  glad  to  havettn e 
address  of  the  Corning  Glass  Company,  with  whom  i  shall 
shortly  communicate. 

It  ocotrrs  to  me  that  there  will  be  two  • 
difficulties  which  will  likely  be  encountered  in  connection 
with  the  use  of  glass  tubing  for  voice  pipe  work;  one  is  the 
danger  of  its  breaking  from  the  shock  of  gun  fire,  and  the 
other  is  the  difficulty  of  getting  watertightness  in  the  com¬ 
partments  through  which  the  tubing  is  to  pass. 

In  our  previous  discussion  of  the  subject 
I  failed  to  point  out  that  the  question  of  watertightness 
was  a  very  important  one.  Also,  that  the  question  of  weight 
might  become  prohibitive .  1  shall  oertainly  give  the  matter 

my  olosest  attention. 

In  connection  with  the  1"  pneumatic  tube 
aystem.  This  has  been  considered  at  times  and  “would  work 
out  very  well  if  it  were  not  for  the  fact  that  this  means  ox 
communication  is  entirely  too  slow  when  a  T®ssel  * 

The  distance  of  the  enemy  changes  very  rapidly,  particularly 
with  high  speed  craft,  and  it  becomes  very  neoesBary  to  be 
able  to  announce  ranges  accurately  in  a  very  f ow  + Rn 

this  tube  system  would  hardly  meet  these  requirements. 

j  reoently  visited  the  Bureau  of  Con¬ 
struction  and  Kepair  in  Washington  and  talked  voice  pipes  at 
some  considerable  length  with  the  representatives  of  teat 
Bureau  and  the  Bureau  of  Ordnance,  and  I  find  them  to  be  very 
much  interested  in  the  subject.  I  am  therefore  sending  un¬ 
officially  to-day,  a  proposed  system  of  voice  tubes  for  some 
n-F  the  new  destroyers. 


Deo.  16,  1916.  CG. 


I  enclose  herewith  a  copy  of'.-.the  letter  I  have 
thus  written  together  with  blueprint  and  two  photographs 
illustrating  the  proposed  method  of  using  the  'Duplex 
mouthpiece , 


Y/hen  Mr.  Hutchison  was  here  with  you  I  had  a  brief 
talk  with  him  concerning  the  feasibility  and  advisability 
of  using  smaller  tubes  on  our  BhipB  and  running  them  in 
parallel  and  then  bringing  them  together  in  duplex  and  even 
triplex  mouthpiece b. 


May  I  therefore  venture  to  again  trespass  on  your 
valuable  time  and  ask  your  criticism  on  the  "Duplex"  mouth¬ 
piece  shown  on  the  plan,  with  reference  to  the  following 
points :  a/  a--  - 

(a)  The  angle  of  taper  vfrrtihn  pas  from  whioh 
the  twin  mouthpieces  are  to  be  made  up  -  what  will  be 
the  probable  effect  on  the  distinctness  of  speech  that 
will  result  from  the  adoption  of  a  semi-circular  en¬ 
trance  gradually  tapering  to  a  circular  outlet  at  the 
lower  end  of  the  ’’Duplex"  mouthpiece. 


Yours  very  tXly,

My  dear  Betiret:- 

I  am  forwarding  herewith  an  outline  arrange¬ 
ment  showing  a  proposed  system  of  voioe  tubes  for  fire  oon- 
trol  on  the  destroyer  class  75  to  94.  This  diagram  is  marked 
up  with  tho  sizes  of  the  tubing  and  with  sufficiently  gonoral 
and  detail  information  so  that  if  the  powerB  that  bo  want  to 
develops  it  for  official  purposes  this  can  easily  be  done  with 
the  data  furnished. 


I  am  writing  to  Mr.  Thos.  A.  Edison  to-day, 
sending  him  a  copy  of  tho  blueprint  and  asking  hiB  oritioism 
on  the  "Duplex"  mouthpioco ,  primarily  with  reference  to  the 
soml-oiroular  flattening  of  tho  two  oones  whore  they  crane 
together. 

I  will  let  you  know  what  he  says  Just  as  Boon 
as  I  get  the  information. 


Personally  from  my  experience  I  have  no 
honitanoy  whatever  in  recommending  the  adoption  of  the  arrange¬ 
ment  shown  on  ths  plan. 


I  also  onolOBe  a  photographs  which  show  about 
the  way  the  tube  would  look,  and  also  tho  position  of  the 
hands  when  ooramunicating  through  both  halves  of  tho  "Duplex 
mouthpiece.  If  one  desires  to  communicate  through  only  one- 
half  of  the  "Duplox"  mouthpiece  they  Bimply  have  to  place  tho

mouth  a  little  closer  to  the  mouthpiece  and  speak  through 
the  half  through  whioh' they  aoBiro  to  ooramunioate . 

I  am  enclosing  duplicate  aopioB  of  my  letter  to 
l!r-  Edison,  and  also  this  letter  to  you,  so  that  you  may

Mr.  Thomas  A.  Edison 
Edison  Laboratory 
West  Orange,  H.  J. 

Dear  Mr.  Edison: 

1  am  sending  you  herewith  reportB  on  the  places 
I  have  recently  visited  in  the  Sandy  Hook  district. 

I  have  interviewed  a  large  number  of  men,  in¬ 
spected  residences  and  public  buildings,  and  covered  the 
territory  thoroughly.  This  section  is  inferior  to  none 
for  residential  purposes. 

Climatic  conditions  are  practically  ideal.  The 
rich  soil  produces  abundant  and  choice  vegetables  and 
fruits.  Vast  quantities  of  fish  and  shell-fish  are  ob¬ 
tained  fresh  from  the  ooean  and  along  the  shores.  Fresh 
poultry  and  eggs  may  be  obtained  the  year  round;. 

Pure  water  is  plentiful.  Transportation  facil¬ 
ities  are  excellent,  and  the  public  highways  are  almost 
perfect. 

If  we  eliminated  all  other  places  in  this 
section,  the  cities  of  Long  Branch  and  Atlantic  Highlands, 
both  near  Sandy  Hook,  could  house  and  oare  for  five  hun¬ 
dred  families  and  one  hundred  men  if  they  should  seek 
immediate  accommodations  in  these  cities. 

Most  respectfully, 


Iatai  Consulting  Imi® 


OF  THU  TIXTEI3D  STATUS

Mr.  Thomas  E.  Edison, 

So .  Orange ,  N .  J . 

Dear  Mr.  Edison: 

I  have  been  traveling  much  of  the  time  since  our 
meeting,  but  have  had  in  mind  to  drop  you  a  note  expressing 
my  very  deep  appreciation  of  all  you  have  done  in  the 
interests  of  the  Board.  I  regret  exceedingly  that  it  did 
not  seem  wise  to  the  Board  to  follow  exactly  your  recommenda¬ 
tions,  but  in  matters  such  as  this,  I  presume  we  have  to 
make  certain  compromises,  and  if  they  are  wisely  made 
some  times  they  are  for  the  best.  For  instance,  in  this 
case  I  feel  that  the  pork  barrel  stood  solidly  between  the 
wisest  measure  and  the  compromising  measure;  and,  of  course, 
the  future  appropriations  for  the  laboratory  are  imperative. 

But  this  is  written  to  assure  you  that  you  have  been 
an  inspiration  to  us  all  by  your  example;  and  your  devotion 
to  the  cause,  with  the  time  taken  from  your  labors  in  in¬ 
specting  the  various  localities,  touches  us  all  deeply.  So, 
my  dear  Edison,  do  not  for  a  moment  be  discouraged,  because  it 
may  all  come  out  for  the  best,  and  in  any  event  you  have  the 
full  sympathy  and  I  know  the  hearty  appreciation  of  every  ' 
member  of  the  board.  You  have  done  a  big  work  and,  as  stated 
above,  have  been  a  great  inspiration  to  us  all. 

Very  sincerely,

My  dear  Mr.  Edison: 

X  have  received  the  report  or  the  majority  committee  favor¬ 
ing  Annapolis  as  the  site  for  the  laboratory,  and  I  have  also 
your  statement  in  v;hich  you  give  your  reasons  why  you  think  it 
should  be  located  at  Sandy  Hook.  I  have  read  both  with  great 
care,  and  I  need  not  tell  you  with  great  regret,  because  I  had 
hoped  that  the  report  of  the  committee  wculd  be  unanimous.  There 
are  strong  arguments  in  favor  of  each  3ite,  and  you  have  present¬ 
ed  those  favoring  Sandy  Hook  very  clearly  and  very  fully.  The 
majority  members  have  made  a  strong  presentation  of  the  reasons 
which  induced  them  to  consider  Annapolis  the  better  site.  The 
feeling  here  at  the  Department  among  the  experts  is  not  in  favor 
of  either  place;  they  prefer  the  District  of  Columbia.  In  view 
of  these  conflicting  opinions,  it  would  seem  to  me  I  should  ap¬ 
prove  the  majority  report.  I  have  hot  yet  acted,  solely  be¬ 
cause  of  my  deference  to  you  and  my  great  confidence  in  your 
judgment.  I  am  constrained  to  feel  it  is  my  duty  to  approve 
the  report  of  the  majority,  and  I  think  you  will  agree  with  me 
the  fact  should  have  weight,  that  in  constituting  the  Board,  from 
two  members  of  each  society,  I  followed  the  excellent  suggestion 
which  you  made,  and,  while  I  place  much  more  value  upon  your 
opinion  than  upon  the  opinion  of  any  other  member  of  the  Board, 

I  fear  both  of  us  would,  in  a  way,  fail  to  support  the  Board, 


-2- 

which  was  appointed  after  our  conference,  and  that  we  owe  it  to 
them  and  to  the  best  service  of  the  Naval  Consulting  Board  to 
give  heed  to  their  earnest  recommendation. 

I  sent  you  some  days  ago  a  statement  showing  the  amount  of 
land  we  have  at  Annapolis.  We  have  a  depth  of  water  there  of 
nineteen  feet,  and  I  feel  sure  that  with  your  direction  in  the 
way  of  getting  results  quickly  and  the  co-operating  work  of  the 
other  members  of  the  committee,  your  idea  of  the  laboratory  will 
make  it  not  only  of  great  value  to  the  Navy  but  to  the  whole 
country. 

I  had  hoped  that  this  week  I  could  arrange  to  run  over  and 
talk  with  you  about  the  matter,  but  I  am  trying  your  stunt  of 
doing  two  men's  work  in  a  day  and  I  cannot  get  away;  but  I  do 
not  wish  to  take  any  action  until  hear  from  you. 

X  hope  you  will  feel,  even  though  the  views  of  the  majority 
of  the  committee  are  not  in  accordance  with  yours,  that  the  site 
they  recommended  is  one  at  which,  under  your  direc tion  aided  by 
them  great  good  can  be  done,  and  that  we  can  immediately  appoint 
a  building  committee,  of  which  I  wish  you  to  be  chairman,  to  be¬ 
gin  the  work. 

Your  great  service  to  the  country  on  the  Naval  Consulting 
Board  as  well  as  in  other  ways  will  be  of  lasting  value  to  the 
Navy,  and  I  believe  also  to  the  Army,  and  will  for  all  time  be 
an  inspiration  to  the  inventive  and  scientific  genius  of 
America. 

My  wife  joins  me  in  the  hope  that  you  and  Mrs.  Edison  will 
come  down  to  Washington  seme  time  in  January  to  see  us  in  our 


-3- 


home.  V/o  would  greatly  enjoy  a  visit  from  both  of  you. 


Always,

The  apparatus  la  to  be  entirely  automatic, 
and  must  at  frequent  intervale  announce  the  names  of  the 
lighthoueea,  and  also  some  warning  message  such  as  "You 
are  getting  closer j look  out." 

It  is,  of  course,  necessary  to  use  for 
this  purpose  a  phonograph  disc  with  a  diamond  or  sapphire 
stylus. 

I  am  asking  you  therefore  if  you  will  be 
so  kind  as  to  oo-operate  with  the  Navy  and  myself  to  this 
extent,  that  you  will  sell  me  a  twelve  inch  disc  having 
two  circular  (and  not  spiral)  tracks  near  the  outer  cir¬ 
cumference,  say  with  one  half  inoh  separation  between  the 
two  tracks.  In  the  outer  track  record  the  words  "Point 
J.udi'th  Light. "  Repeat  this  phrase  once  for  the  entire 
circumferenoe.  In  the  inner  track  record  the  words  "You 
are  getting  oloeer>look  out,"  or  if  this  phrase  iB  too  long 


Naval  Consulting  Board  and  Related  Wartime  Research  Papers 
Subjects  -  Form  Letters  (1916) 

This  folder  contains  standard  letters  prepared  by  Edison's  personal 
assistant,  William  H.  Meadowcroft,  as  responses  to  the  thousands  of 
unsolicited  communications  that  the  inventor  received  on  war-related  topics. 
At  the  beginning  of  the  folder  is  a  note  from  Meadowcroft  to  Edison  explaining 
the  plan  to  use  the  forms  as  responses  to  "letters  from  unimportant  people." 
The  numbers  at  the  top  of  the  forms  correspond  to  the  notations  (for  example, 
"Form  1")  that  appear  on  many  of  the  incoming  letters  in  this  record  group. 

All  of  the  forms  have  been  selected.  However,  some  of  the  form  letters 
that  were  used  in  later  years  are  not  included  in  this  folder.  Examples  can  be 
found  in  the  "Correspondence"  folders. 


Mr.  Edison:

We  have  quite  a  number  of  letiMrs  come  to  you  in  re- 
gard  to  various  inventions  that  the  inventors  want  to  have  sub¬ 
mitted  to  the  Haval  Consulting  Board.  The  most  important  of 
them  I  have  usually  put  in  your  mail  basket,  but  there  have  been 
a  number  of  other  letters  from  unimportant  people,  and  I  have 
written  letters  to  them  substantially  like  the  copy  attached. 

I  propose  to  use  this  as  a  form  letter  for  what  appear 
to  be  the  unimportant  ones  if  you  approve.  Is  it  all  right?

Naval  Consulting  Board  and  Related  Wartime  Research  Papers 
Correspondence  (1917) 

These  folders  contain  correspondence  and  other  documents  relating  to 
Edison's  role  as  Chairman  (later  President)  of  the  Naval  Consulting  Board 
(NCB),  as  well  as  to  his  personal  naval  research,  which  began  in  1917  shortly 
before  the  United  States  entered  the  war.  The  major  problem  that  occupied 
Edison  and  other  inventors  was  the  preservation  of  merchant  shipping 
caoacitv  in  the  face  of  Germany's  unrestricted  submarine  warfare.  U-boats 
were'sinking  cargo  tonnage  faster  than  it  could  be  replaced, 

Allied  ability  to  continue  the  war.  Research  projects  undertaken  bV  Eb's°" 
his  staff  focused  on  enabling  ships  to  detect  and  evade  torpedoes  and  t 
avoid  being  detected  by  the  enemy. 

Among  the  correspondents  are  Miller  Reese  Hutchison  Edborfc  chief 
engineer  and  personal  representative  who  served  with  him  on  the  NCB  and 
other  Board  members,  including  secretary  Thomas  Robins,  Lawrence 
Addicks,  Leo  H.  Baekeland,  Howard  E.  Coffin,  Hudson  Maxim  Wffliam  L. 
Saunders,  and  Frank  J.  Sprague.  Other  correspondents  include  U  S.  Navy 
officers  George  E.  Burd,  Edward  W.  Eberle,  Miles  A.  Libbey,  and  Clyde  S. 
McDowell,  as  well  as  the  Secretary  of  the  Navy  Josephus  Dan|e|s,  to  whom 
Edison  reported  his  research  results.  Among  the  Edison  expermnenters 
represented  in  the  documents  are  Jerry  T.  Chester.  E.  Rowland  Dawson, 
William  Deans,  Theodore  M.  Edison,  Absalom  M.  Kennedy,  Wilham  H. 
Knierim  Samuel  C.  Shaffner,  Bruce  R.  Silver,  Selden  G.  Warner,  and  Heniy 
G.  Wolfe.  Other  scientists  and  engineers  who  appear  as  correspondents 
include  Karl  T.  Compton,  Charles  Fabry,  Reginald  A.  Fessenden,  Frank  B. 
Jewett  John  W.  Lieb,  Ralph  D.  Mershon,  Ernest  Rutherford,  and  Mina  M. 
Edam’s  brother-in-law,  Hubert  K.  Hitchcock.  There  is  also  correspondence 
with  officials  of  the  Cunard  Steamship  Co.,  including  attorney  Lucius  H.  Beers 
and  U  S.  director  T.  Ashley  Sparks,  and  with  suppliers  of  equipment  and 
materials  such  as  John  A.  Brashear,  Ellwood  Ivins,  and  the  Julius  King 
Optical  Co.  Some  of  the  documents  are  records  of  telephone  cQnversations 
conducted  on  Edison’s  behalf  by  his  personal  assistant  William  H. 
Meadowcroft  or  by  office  assistant  Henry  A.  Altengarten. 

Subjects  relating  to  the  NCB  include  the  organization  of  antisubmarine 
warfare  efforts,  visits  by  distinguished  foreign  scientists,  and  a^mpte  to 
resolve  the  dispute  over  the  location  of  the  Naval  Research  Laboratory. 


Subjects  relating  to  Edison's  personal  research  include  his  summer  use  of  the 
USS  Sachem  at  Sag  Harbor  on  Long  Island  for  underwater  sound  detection 
experiments;  his  work  in  Washington,  D.C.,  beginning  in  October;  and  the 
development  of  various  devices  by  his  experimenters,  including  sulphuric  acid 
smokescreen  shells,  aural  direction  finders,  hydrogen  detectors,  and  a 
remotely  detonated  battlefield  explosive  devised  by  Theodore  Edison.  Other 
documents  concern  the  use  of  Fessenden's  audion-based  oscillator  for 
submarine  detection,  requisitions  of  equipment  and  supplies  from  the  U.S. 
military  and  private  companies,  ship  defense  and  submarine  evasion  tactics. 
A  small  number  of  unsolicited  inquiries  or  suggestions  to  which  Edison 
prepared  a  draft  reply  have  also  been  selected. 

Approximately  20  percent  of  the  documents  have  been  selected.  The 
unselected  material  consists  primarily  of  unsolicited  offers  or  requests,  most 
of  which  received  a  brief  form  reply.  Other  unselected  documents  include 
letters  of  transmittal  and  acknowledgment,  routine  purchases  and  shipping  of 
equipment  and  supplies,  multiple  copies  of  outgoing  letters  sent  to  many 
similar  recipients,  discussions  of  staff  arrangements  (including  passes  for 
access  to  military  sites),  copies  of  technical  and  strategic  reports  forwarded 
to  Edison  by  other  NCB  members,  routine  telegrams  exchanged  between 
Edison's  employees,  correspondence  on  expense  claims,  blueprints,  and 
oversized  maps  and  charts.

I  take  pleasure  in  sending  you  the 
enclosed  "booklet,  just  published,  believing 
you  will  find  it  interesting  and  important. 

On  ooean  liner,  yacht,  motor  boat,  coastwise 
steamer,  in  the  event  of  aooident  or  disaster, 
the  EVER- WARM  SAFETY- SUIT  will  save  you  from 
drowning  and  protect  you  from  exposure  and  its 
after  effects. 

Its  guarantee  of  safety  makes  a  direct 
personal  appeal  to  all  who  travel  on  water  for 
business  or  pleasure.  The  EVER-WARM  SAFETY- SUIT 
exhibit  and  water  demonstration  will  be  one  of 
the  big  attractions  at  the  Motor  Boat  Show  in 
the  Grand  Central  Palace,  January  27th  to 
February  3rd.

call  lor  help  has  been  sent  broadcast  over  the 
ocean,  and,  a  hundred  miles  away,  a  steamer 
turns  about  with  smoke  pouring  from  her  funnels, 
while  her  wireless  crackles  a  message  of  hope. 
You  have  had  barely  time  to  adjust  a  life  pre¬ 
server,  gather  a  few  of  your  most  precious 
possessions  and  scramble  up  to  the  tilted  deck, 
when  you  find  yourself  alloat— submerged  to  the 
neck  in  icy  water.  Before  help  can  reach  you 
several  hours  must  elapse— several  hours  or 
exposure  such  as  no  human  being  can  lioe 
through. 

The  life  preserver  may  support  you,  pending 
the  arrival  of  help,  but  it  olfcrs  no  protection 
from  exposure— it  can  keep  you  neither  warm 
nor  dry— consequently  you  cannot  hope  to  sur¬ 
vive.  The  life  preserver  has  failed.  fills  is 
not  imagination—  it  is  a  proven  fact  that  in  ship¬ 
wreck  more  lives  are  lost  by  exposure  and  its 
after  effects  than  by  drowning. 

THE  REAL  LIFE  PRESERVER 

These  facts  prove  that,  in  addition  to  keep¬ 
ing  one  alloat,  an  effective  life  .saving  device  must 
keep  the  body  warm  and  dry  in  water  for  an 
indefinite  length  of  time;  it  must  keep  the  body 
upright  with  head  well  out  of  water;  it  must  be 
quickly  adjustable  and  proof  against  accident  that 
might  render  it  ineffective;  and  it  should  be 
compact,  light  and  easy  to  carry.  The  Ever- 
Warm  Safety-Suit  is  the  first  and  only  device 
which  answers  fully  all  of  these  requirements. 


GUARANTEES  ABSOLUTE  SAFETY 
This  Safety-Suit  enables  you  to  remain  alloat 
for  an  indefinite  length  of  time  and  to  emerge 
warm  and  dry.  notwithstanding  cold  water,  rough 
sea,  and  strong  wind.  It  contains  a  pocket  large 
enough  to  carry  a  canteen  and  liquid  food  to  last 
the  shipwrecked  48  hours  and  more. 

It  affords  abundant  space  in  which  to  carry 
valuables  or  papers,  with  the  assurance  that 
they  will  remain  dry  and  safe,  whether  in  the 
pockets  of  one’s  clothing  or  otherwise  placed 
within  the  suit.  It  is  equipped  with  a  shrill 
whistle,  readily  accessible,  with  which  to  help 
attract  the  attention  of  rescuers.  It  embodies 
every  device  that  human  ingenuity  can  suggest 
to  insure  your  safety  while  in  the  water. 

It  provides  safety  and  protection  to  sailors 
and  travelers,  whether  on  the  ocean,  on  the 
Great  Lakes— where  in  gales  and  storms  the 
shipwrecked  are  cast  adrift  for  hours  and  oUcn 
days  and  nights —  on  any  body  of  water  where 
boats  capsize,  collide,  become  disabled,  or  meet 
with  other  accidents  which  endanger  life.  \\  ith 
this  wonderful  invention  the  voyager  is  safe  on 
water  anywhere,  at  any  time. 

DESCRIPTION  OF  THE  SUIT 
The  suit  is  made  in  union  style,  with  shoes 
and  mittens  —  all  in  one-piece  —  completely  en¬ 
closing  the  body,  excepting  the  head,  in  u  water¬ 
tight  garment  of  u  special  quality  of  absolutely 
water-proof  muteriul.  The  head  is  protected  by

It  is  so  simply  constructed  that  you  can  slip

You  do  not  remove  your  shoes  or  any  of  your

into  the  suit  clothed  just  as  he  or  she  may  be  at 
the  moment,  close  the  suit  by  means  of  two 
clamps  attached  in  a  convenient  position  in  front, 
snap  the  safety  lock  and  plunge  into  the  water, 
where  they  will  lloat  in  an  upright  position,  head 
and  shoulders  well  above  water.  A  lead  sole 
in  the  bottom  of  each  shoe  of  the  suit  keeps  the

Irange  ,  B.  J. 


February  5,  1917. 


Bear  Sir: 


I  plan  to  bring  before  Saturday’s  meeting  the  following  proposal: 

In  the  event  of  actual  conflict  with  Germany,  the  naval  war  will 
apparently  present  the  main  problem  of  defense  of  surface  craft  against 
mine  and  submarine  torpedo  attack.  We  should  therefore  bring  the  trained 
minds  of  the  country  to  bear  upon  the  particular  problem  involved. 

As  we  have  nothing  to  lose  under  existing  conditions  by  a  public 
statement  of  the  elements  of  these  defensive  problems,  and  as  the  average 
engineer  or  scientist  totally  lacks  the  specialized  information  necessary 
to  enable  him  to  make  possibly  very  valuable  suggestions  us  to  their 
solution,  I  suggest: 

That  a  list  of  definite  problems  he  prepared  together  with  a 
concise  statement  of  their  scope  and  limitations,  and  that  tlieso  be  sent 
at  once  by  the  Laval  Consulting  Board  to  the  principal  engineering  societies 
with  the  request  that  their  general  discussion  be  given  a  prominent  place 
at  their  next  meetings  and  that  copies  of  such  discussions  he  forwarded  at 
onoe  to  the  Heval  Consulting  Board. 


As  an  illustration  we  may  take  the  case  of  possible  means  of 
war  ding  off  a  torpedo  approaching  a  ship.  She  statement  of  conditions 
should  give  the  range,  size,  speed,  momentum,  etc.  of  torpedoes;  a  brief 
description  of  the  gyroscopic  and  pendulum  steering  control;  the  depth  range 
of  operation;  present  means  of  defense  by  nets,  etc.;  Btored  energy  of 
explosive  in  head;  any  scheme  already  proposed  such  as  EXEsknm  creation  of 
•pnwflT-fnT  wnn-netirt  field  to  throw  off  course,  etc.:  and  so  on.  Each 
problem  could  be [boiled  down  to  a  single  sheet.  In  addition  to  the  public 
discussion  any  personal  written  communication  would  he  welcome. 

If  any  latent  ideas  of  value  exist,  this  might  he  the  means  of 
disclosing  them, [and  os  our  enemies  would  not  be  conducting  a  similar 
warfare  on  the  djef ensive ,  the  information  could  do  them  but  little  immediate 
good.

Bear  Mr.  Edison: 


Now  that  the  menaoe  of  the  German  submarine  promises  to  Invade 
American  territorial  waters,  would  it  not  he  wise  to  investigate  further  the 
CAMPBELL  device  for  detection,  capture  and  destruction  of  submerged  submarines? 

Tou  will  remanber  I  exhibited  the  plans  and  specifications  of  this  to  you  In 
June,  1915,  at  Which  time  you  were  good  enough  to  examine  it  and  to  approve  the 
principles  involved  by  an  autograph  memorandum  stating  your  thougit  of  the  prac¬ 
ticability  of  the  device. 

Immediately  after  my  Interview  with  you  I  secured  audience  with 
the  American  representative  of  the  British  Admiralty  and  delivered  to  hhn  collate 
nlans  and  specifications,  etc.,  sinoe  which  time  we  have  had  considerable  corres¬ 
pondence,  b£t  I  have  never  been  able  to  learn  with  certainty  whether  the  Campbell 
principles  were  adopted  by  the  British  Government  or  not. 

We  have  good  reason  for  thinking  that  they  were  but  assume  that 
for  the  purpose  of  absolute  secrecy  no  report  haB  been  made  to  us  and  we  are 
thereforeTwithout  knowledge  of  the  faots  relating  to  the  adoption  and  use  of  the 
principles  of  the  device  by  the  British  Government  or  its  Allies. 

How  this  letter  is  for  the  purpose  of  placing  ourselves  on  record 
as  willing  and  anxious  to  exhibit  to  you  or  your  Advisory  Board  at  any  time  upon 
reasonable  notice  the  complete  device  for  looating  submerged  submarines  and  tti 
m“uaedTor  ?heir  capture  or  destruction.  I  hope  to  hear  from  you  in  relation 
to  this  aubjeot. 


With  kind  personal  regards,  I  a

My  dear  Mr.  Edison: 

This  is  to  acknowledge  the  receipt  * 
of  and  to  thank  you  for  your  letter  of  the  1st  instant. 
Sorry  that  you  cannot  be  with  us  at  the  Committee  meet¬ 
ing  on  Ordnance  and  Explosives,  in  order  that  we  might 
have  the  benefit  of  your  larger  knowledge. 

I  regret  your  accident.  I  do  not  want  to 
presume  to  give  you  advice  or  to  caution  you,  but  I 
will  just  let  drop  the  remark  that  should  anything  hap¬ 
pen  to  wink  out  yuur  life  at  this  time  and  at  this  stage 
of  development  of  the  things  you  have  in  the  making,  it 
would  be  a  human  calamity  of  such  magnitude  as  though 
another  Atlantis  were  to  go  down  under  the  sea.

Gentlemen: - 


In  aocordanoe  with  telephone 
conversation  of  yesterday  and  today,  we  are 
sending  by  your  messenger  two  pairs  of  our 
Dustsafe  goggles  fitted  with  S+AZ  lenses. 

These  lenses  are  a  com¬ 
bination  of  our  Saniweld  and  Akopos  glass  and 
are  partioularly  valuable  for  cutting  off  the 
injurious  part  of  the  light  from  the  aoetyiene  • 
or  hydrogen  toroh. 

These  lenses  are  mounted 
in  our  Dustsafe  frames,  which  will  be  found 
most  oomfortable  for  continuous  wear.  Cups 
may  be  ventilated  by  opening  or  closing  ports 
at  the  sides  and  the  distance  between  lenses 
may  be  altered  as  required  by  twisting  chain, 
which  connects  them.  The  fact  the  cups  are 
of  aluminum  will  permit  of  their  being  bent, 
if  necessary,  to  obtain  a  perfeot  seal  on  the 
oheeks. 

This  goggle  is  being  supplied 
to  many  large  users  of  Industrial  Eye  Protectors 
and  is  meeting  with  exoellent  success. 

We  are  also  sending  three 
pairs  lenses  marked  to  indicate  ^ 
and  are  sent  at  your  suggestion  that  they  be 
submitted  for  approval.  One  pair  marked 
Platweld  are  such  as  we  have  supplied  several 


Companies  for  use  when  melting  platinum.  One 
pair  marked  Arkweld  is  of  much  deeper  color 
and  is  usually  supplied  in  combination  with 
other  glass  for  oar  bon  or  iron  aro  welding. 

The  pair  marked  S+AA  are  much  lighter  in 
tint  and  are  intended  particularly  for  such 
work  as  outting  with  acetylene  torch  or  where 
it  is  necessary  for  the  wearer  to  get  a  better 
view  of  surrounding  objects. 

All  of  these  lenses  are 
supplied  with  thin  oover  glasses  fitted  in 
the  frame  first  in  order  that  the  more 
expensive  tinted  lenses  may  he  protected  from 
sparks  and  heat. 

These  are  being  submitted 
for  your  approval  with  the  understanding 
that  all  or  suoh  parts  as  you  do  not  require 
will  be  returned  to  us. 

Memorandum  is  being  held 
awaiting  your  requisition  after  approval.

HAVA1  COESULTIHG  BQAED 


Mr.  A.  S.  C. 

In  the  belief  that  your  special  knowledge  may  enable  yon  to  con¬ 
tribute  some  helpful  suggestions ,  your  attention  and  cooperation  are  invited 
in  connection  with  the  following  technical  problems,  which  will  be  of  vital 
import  in  the  event  of  this  country's  entering  the  threatened  war: 

A.  Deteotion  of  Submarines, 

B.  Annihilation  of  Submarines  after  Deteotion, 

0.  Defeat  of  a  Torpedo  in  Slight. 

While  these  questions  are  primarily  of  a  military  nature,  and 
therefore  possibly  outside  your  immediate  experience,  military  knowledge  is 
not  necessary  to  their  solution  as  pure  scientific  problems.  For  your 
confidential  information  the  following  brief  statement  is  made  of  matters 
bearing  on  the  subject: 

A.  Submarines  when  fully  submerged  are  totally  blind  and 
helpless  as  offensive  weapons.  They  are  not  deaf  and  dumb  however,  as 
means  of  underwater  communication  have  been  developed. 

Submarines  cannot  safely  exoeed  180  feet  submergenoe,  on 
account  of  oompressive  strains.  If  the  bottom  is  too  deep  for  support 
they  must  keep  in  motion  to  maintain  the  desired  degree  of  submergenoe. 

Four  knotB  an  hour  are  required  for  steerage  way.  At  rest  on  the  bottom 
they  may  remain  submerged  a  couple  of  days. 

A  periscope  is  about  five  inohes  in  diameter  and  extends 
sever ql  feet  above  the  water  when  the  submarine  is  hunting  prey.  The 
range  of  vision  is  limited  by  the  low  elevation  and  at  night  the  periscope 
is  useless. 

TorpedoeB  can  be  launched  by  the  submarine  without  emerging 


-1- 


[ATTACHMENT/ENCLOSURE] 


Ihree  principal  means  of  detecting  submarines  are  available; 

(a)  Detection  of  periscope  by  lookouts  with  marine  glasses,  (b)  Detection  of 
fully  or  partially  submerged  submarines  by  aeroplane  scouts,  (c)  Detection 
of  moving  submarines  by  application  of  underwater  signalling  devices. 

(a)  As  the  range  of  vision  from  the  bridge  of  a  ship  is 
greater  than  from  the  perisoope  of  a  submarine,  the  former  has  the 
opportunity  of  first  discovery  and  escape  by  superior  speed.  Even  a 
submerged  submarine  leaves  a  perceptible  wake. 

(b)  Under  proper  conditions  of  water  and  bottom  submarines 
are  clearly  apparent  to  aeroplanes  even  when  the  former  lie  at  considerable 
depths.  Ihis  method  is  subject  to  many  limitations  in  the  matter  of 
conditions,  however. 

(c)  She  peculiar  noises  of  submarines  in  submerged  operation 
are  clearly  distinguishable  by  submarine  microphones  and  similar  apparatus 
stationed  several  miles  away.  She  use  of  two  or  more  stations  enables 
their  location  by  triangulation,  or  moving  sanatoons  can  tactically  follow 
the  scent  by  means  of  their  own  microphones. 

B.  A  submarine  is  a  very  weaELy  constructed  vessel.  A  shot 
will  readily  pierce  it,  but  unless  fired  at  a  considerable  angle  a  shot 
enters  the  water  but  a  short  distance  before  it  ricochets.  She  detonation 
of  a  powerful  explosive  under  water  even  at  considerable  distances  from  a 
submerged  submarine  will  start  its  seams  or  break  hard  rubber  battery  jars, 

either  damage  forcing  an  emergence. 

Various  net  devices  either  with  or  without  attached  mines 

are  used  to  entrap  submarines. 

Oil  has  been  spread  upon  the  water  with  the  view  of  olouding 
the  periscope.  This  method  has  been  only  partially  successful. 

0.  A  torpedo  is  a  slender  meohanioally  propelled  water  projeotile 


[ATTACHMENT/ENCLOSURE] 


oarrying  in  its  head  a  high  explosive  charge  which  is  detonated  hy  contact 
with  any  obstacle  to  its  flight.  It  may  he  launched  either  above  or 
below  the  surface  of  the  water  by  a  small  charge  of  powder  or  by  compressed 
air.  It  is  driven  by  a  high  speed  engine  and  propel lor,  nsing  heated 
compressed  air,  has  a  range  of  several  miles,  and  for  the  pnrposes  of  this 
disonssion  its  speed  may  be  taken  at  28  knots  an  honr.  It  is  steered 
horizontally  by  a  rudder  controlled  by  a  gyroscope  which  is  set  in  motion 
by  the  act  of  launching,  and  vertically  by  a  rudder  controlled  by  a  pen¬ 
dulum  and  depth  diaphragm  so  that  dven  if  thrown  off  its  course  by  any 
means  it  will  accurately  resume  it  provided  the  mechanism  is  undamaged. 

A  torpedo  is  usually  sent  in  a  horizontal  plane  ten  or 
fifteen  feet  below  the  surface.  It  leaves  a  distinct  wake  due  to  the 
escaping  air.  When  seen  in  time  a  fast  moving  ship  can  evade  it  by 

suitable  steering  manoeuvers. 

A  properly  designed  net  is  an  effective  defense  for  an 
anchored  ship,  but  various  cutting  and  explosive  devices  are  mounted  in  tor¬ 
pedoes  to  overcome  this  obstruction,  and  nets  are  not  practical  for  moving 
ships . 

If  you  have  any  ideas  to  contribute  to  the  cause  of  national 
defense  to  supplement  those  already  confidentially  in  the  hands  of  the  Havy 
Department,  please  communicate  the  fact  at  once  to  the  Secretary,  Haval 
Consulting  Board,  13  Park  How,  Hew  fork  City.  If  sufficient  favorable 
replies  axe  received  a  conference  will  be  called  to  which  those  stating  their 
desire  to  participate  will  be  invited. 

Your  immediate  consideration  is  requested. 

Very  truly  yours,

advised  that  there  is  no  submarine  lamp  on  board.  I  was  naturalist 
on  the  vessel  about  1900  and  the  only  lamps  in  use  at  that  time  were 
similar  to  those  supplied  to  navy  divers,  suitable  for  immersion  to 
moderate  depths.  The  only  reference  to  your  lamp  which  I  can  find  in 
the  Bureau's  records  is  enclosod.  A  description  of  a  low  candle  power

Deep-sea  Lamps. 

Our  deep-sea  cable  is  940  feet  in  length  and  ia  coiled  upon  a 
reel,  from  which  it  may  paid  out  to  any  depth  within  that  limit.  The 
lamps  are  according  to  Edison's  patent,  hut  the  wires  simply  extend 
through  the  bottom  of  the  lamp,  the  endB  being  free.  We  solder  those 
wires  to  our  oable,  insulate  with  gutta-percha,  tape,  and  “insulation 
compound."  The  lamps  are  of  about  42  ohme  resistance  and  are  about 
16  oandlepower.  The  lamps  burn  quite  well  under  water  and  can  be 
seen  very  plainly  at  moderate  deptho,  but  they  disappear  entirely 
when  70  feet  below  the  surface.  We  have  had  the  deep-sea  lamp  down 
about  750  feet.

Dear  Mr. Edison:  - 

Governor  Herrick's  office  has  just  telephoned  me  that  you 
are  having  some  trouble  obtaining  experimental  material  from  us  in  con¬ 
nection  with  some  work  you  are  carrying  on  for  the  government.  I  have  taken 
up  the  matter  with  our  specialty  department  here  and  find  that  all  of  your 
requests  received  up-to-date  have  been  given  reasonably  prompt  attention  and 
if  there  is  something  which  we  have  missed  or  have  not  received,  I  will  be 
glad  to  have  your  secretary  advise  ms  promptly  and  I  assure  you  we  stand 
ready  to  co-operate  to  the  fullest  limit. 

In  order  that  you  may  check  up  your  records  with  ours,  I  wish  to  state  that 
under  date  of  February  6th  we  received  a  telegram  requesting  express  shipment 
of  a  few  plates  of  carbon  for  transmitters  ■£'  thick,  same  grade  as  used  by 
the  Acouaticon  Co.'  We  made  shipment  of  a  half  dozen  samples  on  day  following. 
We  could  not  make  Bhipment  on  the  same  day  wire  waB  received  as  the  express 
companies  had  already  called  at  our  works  and  departed. 

February  9th,  we  received  your  long  telegram  indicating  that  you  wanted  samples 
from  which  you  could  cut  1"  cubes.  My  assistant  gave  this  his  personal 
attention  and  assembled  a  conglomeration  of  different  specimens  of  carbons 
you  mi^it  require  in  your  experimental  work  and  we  were  able  to  make  shipment 
of  this  on  the  10th,  the  day  following  receipt  of  your  telegram.  We  have  an 
acknowledgement  from  your  assistant  under  dote  of  the  12th  stating  the  goods 
had  not  yet  arrived.  This  shipment  went  via  Adame  Express  and  if  for  any

requests  data  relative  to  submarines. 

1.  Mr.  Thomas  A.  Edison,  President,  Naval  Consulting  Board, 
has  requested  this  yard  for  a  list  of  casualties  to  submarine 
engines  compiled  from  the  logs  of  as  many  submarines  as  possible 
for  a  period  of  one  year,  tabulating  the  number  of  times  each 
casualty  has  occurred,  in  order  that  an  idea  of  tile  relative 
need  of  improvement  along  specific  lines  may  be  made. 

As  there  are  no  logs  of  submarines  available  at  this 
yard,  it  is  requested  that  this  information  be  supplied  by 
the  Flotilla  Commander  in  as  much  detail  as  practicable  with 
comment  as  to  whether  or  not  a  better  grade  of  material,  an 
entirely  different  material  more  suitable  to  the  condition  to 
be  met,  or  a  change  of  design,  is  desired. 

S.  It  is  requested  that  this  matter  be  considered  urgent  and 
that  the  correspondence  be  forwarded  through,  or  a  copy  supplied 
to,  this  yard.  ,

Hr.  Thomas  A.  Edison. 

Orange,  II.  J. 

Dear  31r:- 

7/e  desire  to  preface  the  following  by  stating  we  are  absolutely 
at  your  command  in  any  way  we  may  he  of  service. 

Your  present  problem  as  we  understand  it  is,  to  obtain  maximum 
illumination.  She  diameter  of  the  pupil  is  our  base,  and  the  size  of  the 
emerging  pencil  is  the  diameter  of  objective  divided  by  the  power. 

If  we  assume  that  the  avorage  pupil  of  observer  may  equal  a 
diameter  of  0."25  then  power  on  4  inch  objective  must  he  a  great  as  16. 

V/riter  would  suggest  a  3  inch  triplet,  a  few  of  which  wo  have 
in  stock,  made  some  years  ago  to  fill  the  conditions  yon  desire.  The  foc¬ 
al  length  equals,  15. "3  and  the  price  in  cell  $  75.00.  One  other  sugges¬ 
tion,  if  your  experiments  arenas  we  feel  confident.»ef  importance,  v.’o  would 
suggest  you  lay  the  entire  optical  problem  before  our  associate  Dr.  Chas. 

S.  Hastings,  248  Bradley  Street,  Hew  Haven,  Conn. 

It  is  perhaps  unnecessary  to  add  that  Dr  Hastings  until  quite 
recently  was  Professor  of  Physics  at  Yale  University.  Some  work  in  connect¬ 
ion  with  the  theory  of  moving  pictures  which  he  did  sbme  years  ago  for  your 
company,  yon  will  doubtless  recall.  All  of  which  is  intord.uctory  to  »he

Dear  Sir:- 


Your  recent  letter  to  Dr.  J.  S.  Ames  was  handed 
to  me  for  reply.  Concerning  the  matter  of  screens  which 
permit  only  ultra-violet  rays  to  pass  through  them,  I  would 
say  thaTTto  my  knowledge,  there  are  none  such.  However, 
the  visible  spectrum  may  be  weakened  very  much  relative  to  the 
ultra-violet  by  the  methods  to  be  outlined  presently.  Possibly 
!>  combination  of  two  or  more  of  such  screens  would  serve  your 
purpose.  As  a  Bouree  of  light,  nothing  is  better  than  an 
arc  playing  between  rods  of  iron  (  a  mercury  vapor  arc  is  also 
very  good).  The  following  screens  are  known  to  be  fairly 
transparent  to  the  ultra-violet: 


Dense  Cobalt  (blue)  glass  one  of  whose  sides  is 
coated  with  gelatine  impregnated  with  Uitroso- 
dimethylaniline . 


2.  A  plate  of  polished  quartz  heavily  silvered  (the 
silver  is  almost  entirely  transparent  at  wave 
length  3100  A.V. 


3.  A  polished  crystal  of  Ilickel-Ammonium  sulphate. 


4.  A  quartz  bulb  filled  with  Bromine  vapor. 

6.  A  layer  of  solution  of  Hi-Amrionium  Sulphate  and  Co  S04. 


If  these  suggestions  prove  worthless, 
beppleased  to  look  up  some  more  if  you  will  let  me 
you. 


I  shall 
hoar  from 


Very  sincerely.

Mr.  Meadowcroft,  Secretary  to 
Mr.  Thomas  X.  Edison, 

East  Orange,  N.  J,, 

My  dear  Sirs- 

I  received  last  evening  your  telegram  of  February 

20th  reading: 

"Please  do  not  go  to  any  further  trouble  I  will 
get  Mathematician  around  here". 

I  hope  that  you  may  be  successful  in  securing  the  services 
of  a  man  who  will  entirely  meet  Mr.  Edison's  requirements. 

As  mentioned  to  you  over  the  telephone  we  had  in  mind 
Mr.  M.  A.  Rusher  who  is  entirely  familiar  with  the  use  of 
ordinary  differential  equations  and  also  with  some  of  the 
simpler  partial  differential  equations,  and  as  a  matter  of 
accomodation  to  Mr.  Edison  we  would  have  been  happy  to  arrange 
to  let  him  have  Mr.  Rusher's  services  for  a  period  of  two  or 
more  weeks  during  which  he  might  have  required  them. 

Mr.  Stevenson,  the  other  man  whom  I  mentioned  to  you 
over  the  telephone,  could  not  have  devoted  more  than  two  weeks 
to  this  outside  work  without  having  put  back  his  work  at  Union 
College  for  the  entire  year.  Mr.  Stevenson  is  not  only 
familiar  with  the  use  of  the  equations  above  referred  to  but 
also  with  the  following: 

"Bessellb  Function,  Legendre's  function. 

Spherical  Harmonics,  Potential  function  and  such  tables 
as  those  of  Jonke  and  Ennde. 


GENERAL  ELECTRIC  COMPANY  1 

If  you  should  find  that  at  a  later  date  we  could 
be  of  any  service  to  Mr.  Edison,  X  certainly  trust  that 
you  will  not  hesitate  to  let  us  know. 

Very  truly-yours.

•I  havp  just  received  your  circular 
addroosod  to'- -the  members’  of  tho  Society,  and 
entitled  "A  coll  to  Duty" . 

will  you  please  ask  tho  Society  at

who  is  expert  in  tho  highor  mathematics,  who 
would  do  some  work  in  the  ovoning  at  homo  in 
connection  with  somo  Government  experiments. 


Answering  your  letter  to  the  Secretary,  all 


of  Mr.  Edison's  reports  have  been  received.  The 
delay  in  his  hearing  from  them  is  doubtless  due  to  the 
fact  that  before  preparing  a  response  the  offices  of  the 
department  concerned  have  wished  to  look  into  each 
suggestion  most  carefully. 

If  you  will  allow  me,  I  would  like  to  suggest 
that  we  be  furnished  with  a  duplicate  copy  of  each  of 
Mr.  Edison's  communications.  The  Secretary's  files  oM— 
purely  for  peroonal  letters,  all  communications  of  an 
official  nature  properly  going  through  the  official  depart¬ 
ment  files.  If  we  could  have  a  duplicate  of  Mr.  Edison's 
letters,  we  could  keep  here  a  private  file  for  the  Secretary, 
sending  to  the  Department  such  communications  as  are 
entirely  official.  In  order  to  have  this  file  complete, 
would  you  be  kind  enough  to  send  me  a  copy  of  each  of 
Mr.  Edison's  six  reports  already  submitted?

My  dear  Ur.  Ueadowcroft: 

Mr.  Newcomb,  the  young  man  I  had  in  mind  when  we  had 
our  conversation  over  the  telephone  yesterday,  wants  to  come  to 
your  laboratory  for  two  or  three  weeks,  but  since  Dr.  filliarc 
L.  Robb,  cur  Professor  of  Electrical  Engineering,  has  most  to  do 
with  him  as  a  post-graduate  student,  he  wishes  to  ask  the  advice 
cf  Dr.  Robb,  who  is  at  present  in  New  York  but  will  return  to¬ 
morrow,  Sunday.  Mr.  Newcomb  will  see  him  Sunday  and  will  then 
advise  you  or  may  start  immediately  for  the  laboratory.  You 
will  find  him  an  earnest  and  able  man.  As  I  told  you,  however, 

most  of  his  work  for  the  l3t  three  years  has  been  in  Electricity 
and  not  in  General  Physios.  I  have  just  told  him  to  send  you  a 
day  letter  giving  the  information  you  will  find  here. 


Very  sincerely  yours,

Ur.  Thomas  A.  Edison,  ji 

Orange,  B.J. 

Dear  Mr.  Edison: 

As  yon  Know,  we  had  Mr.  Fay,  of  the  Submarine 
Signalling  Company,  before  the  Board  at  the  last  meeting. 

That  Company  has  contributed  to  submarine  detection  and 
submarine  communication  for  the  Allies.  The  Committee 
on  Special  Problems  spent  Friday  with  the  Signalling 
Company  on  Boston  Herbor,  and  saw  such  tests  as  you  are 
probably  familiar  with.  The  outcome  of  this  step  is  prao- 
tioally  the  following: 

An  experimental  station  9hould  be  erected  on 
shore  whioh  could  be  connected  to  various  receivers,  micro¬ 
phones,  or  oscillators,  plaoed  in  sufficient  depth  of  water 
to  remove  as  far  as  possible  uninteresting  sounds,  the  idea 
being  to  learn  by  actual  trial  what  we  may  hope  from  further 
development  of  submarine  signalling,  particularly  with  ref¬ 
erence  to  detecting  or  locating  submarines.  In  the  practical 
execution  of  such  experiments  it  seemed  worth  while  to  elimi- 


nate  the  factors  which  make  rapid  and  careful  work  so 
difficult  at  present.  X  refer  to  the  necessity  of 
going  to  sea  in  small  tugs  in  bad  weather  at  irregular 
periods,  under  very  poor  experimenting  conditidns,  par- 
tioularly  for  hearing  and  the  use  of  sensitive  eleotrioal 
instruments-  It  was  suggested  that  a  small  shore  station 
be  placed  at  some  point  like  Uahant  and  connected  to  sub¬ 
merged  receivers,  and  that  in  this  connection  available 
types  of  amplifying  and  receiving  apparatus  be  tried, 
later  on  we  were  led  to  believe  that  this  might  be  dupli¬ 
cating  work  you  were  Planning  to  do,  and  we  should  like 
to  know  if  you  will  advise  us. 

We  should  like  to  assist  in  the  establishment 
of  such  an  experimenting  station  and  help  to  arrange  that 
ideas  not  only  of  the  Subnarine  Signalling  Company,  but 
also  of  others,  might  be  tried  out  under  favorable  conditions, 
For  this  reason,  the  station  should  be  one  whose  necessary 
expenses  are  borne  by  the  government.  Y/e  could  well  estab¬ 
lish  at  once  such  a  station,  even  if  it  were  not  entirely 
suited  for  all  the  various  kinds  of  development  work  the 


If,  on  the  other  hand,  you  prefer  to  see  thi 
type  of  work  undertaken  hy  some  existing  bureau  of  the 
United  States,  will  you  kindly  inform  me  at  onoe,  as  I 
will  then  wish  to  get  permission  to  consult  the  Bureau 
of  Standards  as  the  next  most  logical  step. 

I  have  not  bothered  you  by  a  personal  visit, 
tho  I  should  have  preferred  it  to  writing,  except  for  its 
longer  interference  with  your  work,  but  I  hope  I  may  re¬ 
ceive  an  early  reply. 

Yours  very  truly,

THE  SECRETARY  OF  THE  NAVY. 

WASHINGTON. 

February  26,  1917. 


My  dear  Mr.  Meadowcroft: 

I  am  In  receipt  of  your  letter  of  the  26th.  Pro¬ 
ceedings  of  the  Naval  Institute  have  been  published  since 
1874.  We  have  only  one  complete  set  on  file  here  in  the 
Library.  It  is  possible  that  there  maybe  a  complete 
set  on  file  in  New  York.  This  I  am  endeavoring  to  as¬ 
certain.  You  will  hear  from  me  in  another  day  or  two. 

Is  it  possible  that  Mr.  Edison  desires  a  complete  set 
since  1874?  I  take  it  that. he  is  interested  more  par¬ 
ticularly  in  the  recent  issues,  say  for  the  past  ten 
years. 

Sincerely  yours.

Dear  Dr.  Haclawrin: 

I  have  received  your  favor  of  the  27th  ultimo, 
and  have  shown  it  to  Hr.  Edison.  He  appreciates  very  much  your 
efforts  to  assist  him  in  reoamending  some  young  men  to  help 
him  in  hl3  Government  experiments,  and  realizes  the  difficulties 
will  oil  lie  in  your  way.  Of  course,  he  would  not  wish  for  a 
moment  to  have  any  of  your  young  men  imperil  their  chance  of 
graduation,  and  wishes  me  to  say  to  you  since  X  telephoned  you  a 
few  days  ago,  ho  has  been  able  to  get  a  fow  young  men,  and  can 
now  avail  himself  of  the  services  of  some  more  from  local 
institutions. 

Onoe  more  thanking  you  for  your  efforts  in 
Hr.  Edison's  behalf,  I  remain. 

Yours  very  truly. 

Assistant  to  Hr.  Edison.

Dear  Dr.  Finley: 

Allow  me  to  thank  you  for  your  kind  favor  of  the 
27th  ultimo,  and.  also  to  express  Hr.  Edison's  thanks  to  you  for 
having  boon  Instrumental  in  sending  to  him  the  two  young  men 
mentioned  therein.  Hr.  V.ooden  and  Hr.  Curt  arrived  here  promptly 
on  Monday  morning,  and  Hr.  Edison  put  them  to  work  right  away. 
VUoy  are  now  very  busy  helping  him  in  his  experiments. 

Hr.  Hewcomb  also  came  on  Monday  morning  and 
remained  through  the  day,  but  he  returned  home  and  wo  2iave  re¬ 
ceived  a  letter  from  him  saying  that  he  would  scarcely  wish  to 
neglect  ills  regular  work. 

Hr.  Edison  thinks,  that  he  will  bo’  able  to 
obtain  one  or  two  more  young  men  locally,  but  if  he  finds  he 
cannot,  ho  will  avail  himself  of  your  kind  offer  of  further 
assistance. 

With  renewed  thanks,  1  retain, 

Yours  very  truly.

y  dear  Mr.  Keadoworoft: 


Following  our  conversation  of  Vues day,  I  believe  Mr.  Frederick  c 
our  laboratories  has  given  you  information  for  Mr.  Edison's 
as  follows: 

Our  70  ohm  watch  case  receiver  is  known  as  the  #128  type.  Its  wind¬ 
ing  consists  of  a  total  of  1475  turns  #35  S.S.l'.C.C.  per  receiver  (half  this 
number  of  turns  per  spool). 

Our  #146  type  receiver  is  a  watch  case  receiver  unit  of  650  ohms 
resistance  wound  with  4226  turns  #40  S.S.S.C.O.  per  receiver  (half  this  number 
of  turns  per  qsool).  ;  j 

V/e  have  in  the  past  made  a  1000  ohra  receiver  unit  consisting  of  a 
#128  type  unit  wound  with  a  total  of  6400  turns  #40  B.E.C.C.  (3200  turns  per 
spool) . 

We  have  also  trade  a  1500  ohm  unit  consisting  of  a  #128  type  unit 
wound  with  8600  turns  #40  B.E.O.C.  (4300  turns  per  spool). 


e  first  two  types,  l.e.,  70  and  650  ohm  reoeivers,  we. have 


stook.  The  latter  two  types  we  do  not  carry  in  stock,  but  could  in  case  of 
an  emergency,  rewind  in  the  Model  Shop  in  very  limited  numbers,  reoeivers  of 
the  #128  type  within  two  days. 

We  do  not  have  any  2000  or  3000  ohm  receivers,  and  have, inters 


Mr.W.H.Meadoworoft  -  2  - 

pretod  the  request  for  information  on  1000, 2000  and  3000  ohm  rooeivers  to  apply 
to  pairs  of  receivers  having  a  total  resistance  of  1000„  2000  and  3000  ohms. 

I  am  confirming  this  information  by  letter  so  as  to  eliminate  pos¬ 
sibilities  of  error. 

Yours  truly. 


Chief  Engineer.

Dear  Sir:- 


I  on  engaged  in  making  some  experiments  for  the 
Government.  In  the  course  of  those  experiments  it  iz  quite 
possiblo  that  I  ohall  want  to  havo  access  to  various  loea- 
tiona  in  the  lower  Bay,  wore  I  could  handle  some  oxuoriraonts 
from  a  Dock  into  IS  or  20  foet  of  water.  Swinbourn  iDland 
would  bo  a  pood  location. from  tho  point. of  view  of  oxperi-  ' 
neats,  but  I  understand  that  it  is  uced  as  a  Quarantine 
station  for  tho  detention  of  contagious  diseases. 

Of  coureo,  I  wouia  not  like  to  send  men  down  whore 
tho-'  would  bo  in  danger  of  contagion.  Eherofore  I  am  writ¬ 
ing  to  ask  (assuming  that  permission  would  bo  granted )  whether 
there  is .a  Bock  far-  oriough  removed  -from  danper“of  contapion, 
Where  a  few  men  could  land  an  parforn  some  experiments  with 
apparatus  that  I  should  want  to  low or  into  tho  water. 

I  think  you  will  porhaps  undorctand  from  tho  abovo 
just  what  I  want  to  accomplish,  and  should  bo  .obliged  if  you 
will  give  no -as  much  information  you  con1  on  tho  sub Joe t,  and 
also  advising  mo  as  to  whore  I  shall  get  permission  to  con¬ 
duct  those  oxpofimonts,  assuming  dihat-  it.  would  bo  safe  to 
send  mon  down  there. 

I  shall  appreciate  an  early  reply,  and  thank  you  • 
in  advance  for  your  courtesy. 

Yours  very  truly.

We  received  the  Henderson  shipment  promptly  and  1  am  sending  you  under 
separate  cover  six  lots  from  the  Henderson  seeds,  carbonized  with 
Treatment  A.  This  treatment  la  exactly  the  same  as  was  given  the 
original  lot  sent  you  Saturday  marked  1-A  and  2-A  and  the  sample  lot  we 
are  forwarding  you  today  consists  of  the  following  Beeds,  each  package 
being  marked  A: 

Turnip,  Early  White  Milan  -  --  --  --  --  --  --  -  -A-

This  will  serve  to  give  you  an  idea  as  to  whether  this  process  approximates 
Mr.  Edison's  expectations. 

In  the  meantime  we  are  reserving  the  balance  of  the  seeds  for  B  and  C  experi¬

Dear  Ur.  Edi?on:- 

I  have' just -received  your  letter  of  the  8th  stating  you  are  not 
getting  results  with  seeds  sent.  I  am  afraid  we  are  working  at  cross  purposes. 

Thus  far,  please  keep  in  mind,  we  have  had  no  information  from  your  department 
indicating  the  object  you  wish  to  attain.  I  think  we  can  help  you  more  intelligently 
if  you  will  give  us  some  idea  of  what  you  are  endeavoring  to  accomplish  or  in  other 
words,  give  us  some  idea  of  the  function  to  be  performed  by  carbonised  seeds. 

Although  there  has  been  nothing  in  your  correspondence,  we  have  assumed  that  the 
globular  carbon,  such  as  used  by  th  e  Ac  oust  icon  Co.  has  perhaps  not  quite  suited 
your  purpose  and  that  by  the  use  of  seeds'  you  wish  to  obtain  something  more 
eenitive  and  it  is  on  this  theory  that  we  have  been  working. 

Please  understand  we  are  not  trying  to  pry  into  your  experiments  except  to  the  ex¬ 
tent  of  getting  some  idea  as  to  why  the  globular  carbonB  such  as  aroused  by  tele¬ 
phone  manufacturers  are  not  suited  for  your  purpose  and  wherein  you  wish  a  globular 
carbon  to  differ  from  that  generally  used. 

Fearing  that  you  may  be  laboring  under  a  misapprehension,  I  mi ght  state  also  that 
the  globular  carbon  used  by  telephone  companies  is  not  manufactured  from  seeds  but 
is  small  carbon  pellets  manufactured  in  the  green  state  as  near  spherical  as 
possible  and  then  carbonized. 

If  you  can  give  us  a  little  more  information,  perhaps  with  our  knowledge  of  carbon 
making,  we  may  bo  able  , to  assist  you  in  producing  that  which  you  require  and  do 
it  more  intelligently.  At  the  present  time  we  are  working  in  the  dark  and  merely 
carrying  out  your  instructions  to  carbonize  the  various  seede  which  have  been  Bent 


We  will  be  glad  to  co-operate  with  you  to  the  fullest  limit  and  anything  you  may 
say  to  us,  you  can  rest  assured  will  be  treated  confidentially. 


Yours  very  truly,

appearance  of  them.  He  says  they  look  bettor  than  those  carbonised 
by  the  "A"  process. 

It  is  quite  an  improvement  to  put  these  samples  in

thank  you  for  your  courteous  attention  in  this  matter.

' -She  .last  lot  of  carbonized  soodo,

I  had  supposed,  fron-the  fact  of  the

made,  from  seeds ,  and  I  thought  that  I  could 
get  some  that  might  have  a  poliGhod  surface,

1  have  read  with  interest  about  your  submission  to  the  Secretary 
of  the  Navy  of  your  minority  report  favoring  Sandy  Hook,  or,  as  one 
newspaper  put  it,  as  favoring  New  York. 

The  Plum  Island  reservation  of  the  United  States  Government,  lo¬ 
cated  at  sheepshead  Bay  and  opposite  Manhattan  Beach  and  diagonally  be¬ 
hind  the  new  great  Rockaway  fortifications,  with  plenty  of  water  front 
and  but  a  short  distance  from  Ambrose  Channel,  would,  I  feel  confident, 
appeal  to  you  most  favorably  in  comparison  with  Sandy  Hook. 

The  subject  is  of  intense  interest  to  the  citizens  of  Greater  New 
York  and  the  matter  has  been  carefully  considered  by  the  of f lei al s  of 
the  City. 


Mr.  R.  A.  C.  Smith,  Commissioner  of  Docks,  knows  this  territory 
and  the  conditions  very  well  and  could  enlighten  you  on  all  the  details 
thereof  in  a  brief  interview  or  by  correspondence.  I  think  you  should 
know  the  facts  if  you  have  not  already  been  informed  of  them. 


Personally,  I  can  see  no  objection  why  this  institution  should  not 
be  located  near  New  York  City.  The  question  of  impregnability  is  a 
minor  one,  for  New  York  should  be  worth  saving.  Our  national  defences 
of  New  York  City  should  be  positively  impregnable  before  any  other  sec¬ 
tion  of  the  country  is  made  so,  and  I  am  inclined  to  think  that  it  can 
be  made  so  as  readily  as  any  other  section  of  the  country.  The  brain 
power  of  the  nation  is  also  centred  within  800  miles  of  the  Metropolis, 
and  the  many  other  advantages  toward  bringing  this  institution  to  the 
vicinity  of  New  York  in  my  opinion  proves  the  wisdom  of  your  viewpoint. 

If  you  are  not  arbitrarily  in  favor  of  Sandy  Hook,  would  you  be 
willing  to  submit  a  supplemental  report  on  Plum  Island  should  it  appeal 
to  you  as  an  alternative  location?

Dear  Sir: 

I  take  great  pleasure  in  sending  to  you  a  copy  of  QST. 

This  is  the  official  organ  of  The  American  Radio  Relay  League, 
an  organization  of  the  amateurs.  .  We  have  succeeded  in  relaying 
a  message  from  New  York, City  to  Los  Angeles  and  back  in  less  than

amateur  system  is  extended  all  over  the  country  and  reachable  not 
only  by  wireless  but  through  QST.  I  fel  t  that  you  would  surely 
be  interested  if  you  have  not  already  heard  of  our  League.  We 
wish  to  assure  you  that  our  membership  can  be  counted  on  in  time 
of  necessity.  It  might  also  be  of  great  value  in  certain  scientif¬

sets  in  all  parts  of  the  country,  we  already  have  them  and  could 
be  commandered  at  a  moment’s  notice.

Dear  Mr.  Edison:- 


Replying  to  youre  of  the  12th,  we  are  sorry  we 
cannot  help  you  out  on  the  matter  of  polishing  aoousticon  halls. 

This  would  be  a  very  hard  proposition  on  account  of  the  fact  that 
the  balls  are  hollow  and  naturally  will  not  stand  much  strain. 

If  polished  surfaces  are  essential  in  your  experiments,  we  believe 
you  will  obtain  the  required  results  by  carrying  on  your  experiments 
with  our  acousticon  balls,  rather  than  seeds  because  you  will  find 
the  crushing  strength  of  the  acousticon  ballB  1b  much  greater  than 
that  of  seeds. 

With  your  extensive  laboratories,  we  believe  you  are  in  as  good  a 
position  to  carry  on  these  polishing  experiments  sb  we  are  because 
of  the  fact  that  we  are  loaded  to  the  guards  with  work  of  all  character 
and  to  carry  on  polifching  experiments  would  mean  designing  a  machine  of 
some  sort  for  this  purpose  which  would  not  only  require  time  in  design¬ 
ing  but  would  also  moan  a  delay  in  the  construction  of  same  owing  to 
the  fact  that  our  machine  shop  it  now  three  to  four  months'  behind 
in  their  work.

(Excerpt  of  Report  of  Mr.  Bassett) 

Every  one  was  on  hand  In  Boston,  at  the  appointed  time, 

Friday  morning.  We  all  went  to  the  Navy  Yard  and  were  taken  from 
there  aboard  a  Navy  tug  out  to  the  Boston  Light  ship.  There  we 
examined  sn  installation  of  the  Fessenden  oscillator  and  saw 
it  operate.  We  then  went  off  about  five  miles  from  the  lightship 
and  received  signals  from  them  through  the  water.  We  received 
both  with  microphones  and  with  another  oscillator.  The  oscillator 
sounded  clearer  as  a  receiver  than  the  microphones.  But  the 
microphones  were  not  very  sensitive  as  they  were  not  built  for 
delicate  work.- 

On  our  return  to  Boston  we  went  to  Professor  Fessenden's 
Laboratory  and  met  him  personally.  He  is  working  on  telephoning 
with  his  oscillator  and  has  been  successful  up  to  distances  ex- 
oeeding  one  half  mil©* 

Saturday  morning  we  went  through  the  sea-sled  factory  where 
they  had  some  fifty  foot  hydroplanes  under  construction.  The 
sea-sled  seems  to  be  a  most  interesting  and  revolutionary  advance  in 
large  speed  boats .

Mr.  Lawrence  Addlcks,

Dear  Mr.  Addioka: 


SUBJECT :  Report  on  Special  Experiments  on  Submarine 
Net,  Made  on  Nest  Coast  of  Florida, 

March,  1917. 


The  very  great  usefulness  of  some  form  of  electric 
circuit  controlling  net  is  so  obvious,  its  application  could 
be  utilized  in  bo  many  ways,  and  it  having  been  brought  to  the 
attention  of  some  members  of  the  Board,  X  thought  it  best  to 
make  actual  trials  on  something  simulating  a  full  Beale,  to 
ascertain  the  exact  conditions  that  will  be  found  to  exist 
where  nets  made  up  of  alternately  rigidly  attached  and  in¬ 
sulated  crossings  of  the  lateral  and  vertical  members  to  make 
a  net,  which,  although  mechanically,  constitutes  a  single  unit, 
would  be  electrically  two  separate  and  distinct  units,  with  . 
opposite  sides  of  all  meshes  of  opposite  polarity.  The  various 
forms  in  which  the  modern  practically  indestructible  insulating 
members  can  be  constructed  render  such  a  net  perfectly  practicable 
from  a  mechanical  standpoint,  and  it  was  to  test  out  the 
electrical  possibilities  that  the  experiments  were  undertaken. 

•The  experiments  were  also  designed  to  test  out  and 
setiie  once  for  all  the  practical  operation  of  the ' so-called 
critical  electrolytic  voltage,  which  is  supposed  to  approximate 


[ATTACHMENT/ENCLOSURE] 


Mr.  Addloks  -  2. 

1.6  voltaj  the  practical  application  being  to  see  whether 
lower  voltages  than  this  could  be  utilized  to  distinguish  dead 
short  circuits  from  the  circuit  which  included  the  sea  water 
as  electrolyte. 

The  place  of  the  experiment  was  the  west  shore  of  the 
Keys,  lying  some  eight  miles  west  of  Belaire,  Florida. 

The  water  was  clear  and  warm,  so  that  the  various 
persona  could  be  depended  upon  to  work  continuously  in  their 
bathing  .suits  in  the  surf.  The  water  was  the  standard  brine 
that  obtains  in  the  Gulf  of  Mexico.  The  tides  were  about  one 
foot  six,  and  low  tide  was  selected  as  the  beginning  of  the 
experiment,  it  being  about  1:30  P.M.  Qalvanized  wire  No*  12 
gauge,  well  selected,  was  used,  giving  about  2$  square  feet 
of  exposed  area  for  each  1,000  feet  of  length.  This  measures 
on  the  order  of  six  ohms  per  thousand  feet.  It  was  found  to 
be  thoroughly  insulated  when  lying  upon  the  dry  hot  sand. 

Three  of  these  strands,  with  ends  fastened  to  Georgia 
pine  stakes,  and  each  end  brought  out  on  the  shore,  were  strung 
along  the  coast,  the  stakes  being  1,000  feet  apart.  The  two 
outside  wires  were  distributed  as  follows  with  reference  to  the 
central  wire  —  the  outer  one  toward  the  sea,  being  about  two 
feet,  arid  the  in-shore  one,  ten  feet*-  all  wires  being  submerged 
Different  voltages  were  now  applied  between  the  wires  at  one  end 
and  the  wires  were  carefully  short  circuited,  commencing  at  the 
far  end  and  coming  forward  to  within  a  few  feet  of  the  initial 
immersion. 

There  were  plaoed  in  circuit  a  milliameter  and  voltages 


[ATTACHMENT/ENCLOSURE] 


Mr.  Addioks  -3. 

ranging  from  35/100  of  a  volt  (secured  by  placing  a  dry  cell 
and  a  storage  battery  in  opposition)  with  various  farther  ad¬ 
justments  of  voltage  up  to  about  15  volts  -  the  wires  being  also 
tested  by  a  bridge.  The  mean  resistance  between  the  center  wire 
and  either  of  the  outer  wires  was  found  to  be  about  3,3  ohms, 
whloh  was  very  constant. 

It  was  found, even  at  the  lowest  voltage  applied  to  the 
system,  that  in  the  1,000  foot  strands  the  exposed  area  was  of  such 
magnitude  as  to  give  very  complete  conduction  from  wire  to  wire, 
through  the  electrolyte,  so  much  so  that  the  dead  metallic  circuit 
would  not  cause  variation  in  the  amperes  flowing.  This  was  true 
for  short  clrouits  at  the  further  end; and  for  short  circuits 
completed  beneath  the  surface  of  the  water  at  9/l0,  down  to  about 
3/10  of  the  length  of  the  net  nearer  than  this,  the  short  circuit 
when  completed  made  Itself  felt,  but  gave  only  trifling  variations 
in  the  amperes  flowing,  until  within  the  last  100  feet  of  the 
end  at  which  the  instruments  were  located  and  electro-motive 
force  applied.  The  only  indication  that  the  so-called  law  had 
any  effect  whatever  was  that  the  electro-motive  forces  below  1.8 
seemed  to  give  somewhat  more  differential  than  the  eleotro-motive 
forces  above  thiB  point.

COROLPSIONS 

X.  On  the  very  large  exposed  area  the  two  sides  of 
any  electrical  net  would  be  completely  short-circuited  by  the 
high  conductivity  of  the  ocean  water  Itself  at  any  practical 
voltage . 

2.  Practically  no  amount  of  short  circuiting  would  change 
the  electrical  conductivity  of  the  net,  under  conditions  of  e.m.f. 
furnished  from  an  outside  source. 

3.  Nets  or  similar  structures,  employing  electricity 
from  outside  sources  will  operate  as  strictly  short  circuited 
conductors . 

k.  The  conditions  seem  to  prevail  practically  Instantaneously 
upon  contact  being  made.  No  observation  was  made  that  would 
indicate  that  alternating  e.m.f.  would  operate  any  differently 
than  direct.  Mr.  Raymond  suggested  that  the  conditions  would 
probably  be  different  If  the  net  itself  developed  its  own  e.m.f.

It  is  thought  that  the  deterioration  factor  on  the  side  of  the 
net,  which  is  slowly  going  into  solution,  under  these  conditions 
would  probably  render  it  prohibitive,  but  nevertheless  it  might 
be  wise  to  give  further  thought  to  this  particular  feature  in 
some  of  its  aspects.

AUTOMATIC  NETS 

The  moat  effective  way  now  known  to  render  nets  automatic 
is  that  of  placing  in  the  middle  of  quite  extensive  nets  an 
innocent  looking  buoy  of  riveted  boiler  plate.  This  buoy  re¬ 
sembles  a  contact  mine  and  is  just  the  kind  of  thing  that  any  . 
boat  would  naturally  shun.  Any  disturbance  at  any  part  of  the 
net  (i.e.  if  any  portion  of  the  net  takes  on  a  predetermined 
speed  of  knots)  causes  a  sudden  transformation  to  take 
place  in  the  buoy,  which  suddenly  presents  a  twenty  foot  mast 
with  umbrella-like  antennae,  constituting  a  very  simple  wireless 
plant  of  thirty  miles  range,  which  starts  in  and  for  an  hour 
and  a  half  repeats  the  number  of  the  buoy  by  wireless. 

This  has  been  developed  for  England  and  the  Navy  and 
is  a  secret  device,  and  this  information  must  be  treated  in 
strict  confidence.  We  are  just  about  to  test  this  out  on 
No.  1  net  outside  New  York  Harbor.  Later  we  will  probably 
use  our  own  net,  as  the  Harbor  net  is  considered  too  heavy, 
being  made  up  of  5A  cable,  whereas  the  English  mobile  nets 
are  muoh  lighter.

PIG  TORPEDOES 

Special  armament  against  submarines.  This  consists  vir¬ 
tually  of  torpedoes  each  a  little  over  six  inches  in  diameter  and 
five  feet  long,  self-propelled,  operating  at  50  knots,  with  a 
range  of  three  to  four  thousand  yards,  carrying  15  pounds  of  T.N.T., 
and  working  at  any  fixed  depth  between  5  feet  and  1+0  feet,  usually 
being  set  for  21  feet,  which  is  about  the  depth  of  the  middle  of 
the  hull  of  the  submarine  with  a  normal  periscope  exposure. 

The  torpedoes  are  expelled  from  a  very  light  swivel  gun 
held  at  the  shoulder,  sighted  as  in  the  case  of  an  ordinary  shot  gun, 
and  after  being  dropped  into  the  sea  plunge  to  the  set  depth  and 
run  straight  to  the  mark.  It  is  believed  that  these  shots,  which 
can  be  depended  upon  to  travel  under  water,  form  probably  the  best 
defense  against  submarines  for  boats  both  in  and  out  of  the  Navy. 
They  can  be  expelled  at  the  rate  of  from  four  to  six  a  minute  in 
the  general  direction  of  the  submarine,  after  the  periscope  has 
been  detected,  and  it  is  only  necessary  for  one  to  take  effect, 
the  size  of  the  hole  blown  in  standard  submarine  plating  at  the 
depth  of  21  feet  by  12  pounds  T.  N.  T.  being  known  to  be  large 
enough  for  a  man  to  walk  through.  Some  of  the  aviation  officers 
of  both  Army  and  Navy  are  looking  forward  to  this  light  weight 
torpedo  (being  less  than  100  lbs.)  as  the  most  suitable  one  for 
launching  from  aeroplanes  against  submarines  and  all  but  the 
heaviest  naval  and  marine  craft. 

This  has  been  developed  for  the  United  States  Navy  and  is 
a  secret  device,  and  this  information  must  be  treated  in  strict 


confidence .

SUBMARINES 

I.  Indications  of  Presence. 

(a)  Periscope.  White  wake  when  submarine  Is  In  motion, 

constituting  disturbances  of  the  surface,  which  are 
less  and  less  apparent  as  the  submarine  runs  at 
greater  depths.  Captain  Gaunt,  British  Naval  Attache 
told  me  that  the  wake  was  perfectly  apparent  in  all 
but  the  heaviest  sea,  when  the  submarine  was  running 
•  80  feet  submerged,  and  even  then  when  the  observer 

was  dead  aft  or  in  line  of  the  submarine's  travel. 

(b)  Protrusion  of  periscope,  constituting  a  visible  mark 

when  submarine  Is  stationary. 

(c)  Oil  globules,  which  continually  come  to  the  surface 

and  spread  out,  and  it  is  said  can  be  seen  and  traced 
for  considerable  distances,  especially  from  an  aero¬ 
plane  observer. 

Note.  It  is  stated  that  old  whalers  are  the  best 
men  to  use  on  the  bridge  for  detecting  the  presence 
of  submarines,  being  familiar  as  they  are  with  the 
slightest  disturbance  or  abnormal  condition  on  any 
part  of  the  surface  of  the  sea,  usually  imperceptible 
to  the  untrained  eye. 

II.  General  Visibility  from  Aeroplanes 

(a)  It  is  stated  that  a  submarine  has  been  seen  at  Gibraltar 

at  25  fathoms  by  an  aeroplane. 

Note .  Bearing  on  this  subject,  when  the  Great  South 
Bay  is  smooth,  from  an  aeroplane  only  the  bottom  is 
seen,  and  many  accidents  have  happened  by  an  aviator 
coming  down  and  encountering  the  surface  before  he 
supposed  he  had. re ached  the  surface*  The  death  and 
smash-up  within  the  last  three  months  at  Philadelphia 
is  an  instance  of  this  kind. 

(b)  At  anything  but  the  deepest  submersion  when  the  surface 

is  not  too  troubled,  the  big  black  hulk  of  a  submarine 
can  be  easily  seen  from  an  aeroplane  flying  about  500 
feet  above  the  surface.  This  has  been  repeatedly 
demonstrated  In  tests  at  Pensacola. 

lit.  Audibility  • 

As  to  the  audibility  It  would  seem  that  the  low  tones 
can  be  heard  close  by.  One  authority  says  four  miles, 
but  fails  to  say  what  it  was  that  was  heard.  The  high 
note  emanating  from  the  sing  of  the  commutator  can 
be  heard, much  further  --  I  understand  about  fifteen 
miles  in  extreme  cases.

IV.  Protection  against. 


As  protection  against  submarines,  an  explosion  of  the 
nearby  charge  will  certainly  work  disaster  to  a 
submarine.  150  lbs.  of  T.  N.  T.  will  deliver  a  shock 
of  about  260  pounds  per  square  inch  at  110  feet 
from  a  submarine.  A  submarine  Is  built  to  stand 
89  pounds  pressure  per  square  inch,  with  an  unknown 
factor  of  safety  at  250  feet  submergence,  which  it 
approaches  with  great  caution. 


NETS 

Nets  have  been  the  most  fruitful  means  of  capturing 
submarines.  The  nets  are  supported  by  buoys  and  are  dragged 
between  trawlers,  or  emplaced  entirely  free,  the  buoys  being 
provided  with  little  flags,  which  are  watched  constantly  by 
.the  mosquito  fleet.  The  difficulty  with  this  is  that  the 
mosquito  fleet  cannot  live  in  heavy  weather,  and  the  watching 
is  very  difficult  in  fog.  To  such  an  extent  is  this  true  that 
the  Germans  are  said  to  select  heavy  weather  and  fog  conditions 
to  get  through  the  English  Channel  and  other  localities  known 
to  be  protected  by  nets. 

The  submarine  does  not  know  that  it  has  encountered  a 
net  until  the  net  is  folded  back  over  the  submarine  to  a  con¬ 
siderable  extent,  and  it  commences  to  drag  a  large  percentage 
of  the  total  length  of  the  net,  when  it  begins  to  feel  the  re¬ 
tardation.  Some  times  it  can  even  then  back  out  of  the  net 
successfully,  but  in  weather  where  the  mosquito  fleet  can 
operate,  they  see  the  flags  moving  off  and  signal  for  the 
torpedo  boat  destroyer  to  come  with  its  vertical  dropping  bombs. 
These  are  dropped  directly  over  the  acute  angle  of  the  traveling 
net,  and  it  is  said  that  oil  rises”  to  the  surface,  indicating  that 
a  shot  has  taken  effect. 


[ATTACHMENT/ENCLOSURE] 


-5- 

Another  way  has  been  to  attempt  grappling  the  submarine 
and  tipping  her  over  —  thus  killing  the  occupants  -  and 
afterwards  salvaging  the  submarine.  X  have  my  doubts  of  this 
being  true. 

The  so-called  razor  blades  on  the  nose  projections 
of  submarines  as  an  armament  against  nets  are  probably  of  no 
value,  as  the  hard  steel  of  the  wire  and  the  gentle  contact 
would  leave,  the  net  practically  unaffected  by  any  such  device. 
It  is  thought  that  none  but  a  very  comprehensive  use  of  nets 
will  serve  the  purpose.  This  requires  altogether  too  extensive 
a  mosquito  fleet  to  be  practical.  For  instance,  the  stretching 
of  nets  from  Holland  to  the  Norway  coast,  thus  cutting  off  the 
North  Sea,  would  require  about  260  miles  of  nets;  and  in  this 
instance  it  is  contemplated  using  automatic  nets,  whereby 
any  disturbance  in  the  net  by  a  submarine  is  made  known.

DEFENSE  AGAINST  TORPEDOES 

It  is  believed  that  the  Lion  or  equivalent  method  of  nearby 
explosion  may  be  made  effective  in  crippling  oncoming  torpedoes. 

Two  nets:  for  ships  that  are  standing  still  would  be 
effective,  but  nets  at  best  are  very  undesirable,  owing  to  the 
continual  trouble  of  entanglement  with  the  ship's  propelling 
machinery.  The  most  effective  method  is  believed  to  be  the  honey¬ 
combing  of  the  hull  belt  at  the  proper  submergence,  which  is  a 
very  great  gain  from  a  number  of  standpoints,  eliminating  the 
possibility  cf  any  entanglement  with  the  propellers,  being  equally 
serviceable  at  all  speeds,  and  protecting  against  mines  as  well  as 
torpedoes.  The  mines,  as  a  matter  of  fact,  have  less  explosive 
charge  than  the  torpedoes,  except  perhaps  the  rumored  Bhort  range 
torpedoes  the  Germans  are  using  in  their  submarines.  Some  accounts 
give  this  charge  as  high  as  lj.00  pounds,  which  is  not  generally 
believed. 

DEFENSE  AGAINST  SUBMARINES 

The  officers  who  have  in  charge  the  study  of  the  arming  of 
merchant  vessels  tell  me  that  the  conclusion  reached  (whether 
the  advices  are  later  overruled  remains  to  be  seen)  is  that  small 
one-pounders,  semi-automatic,  shooting  about  twenty  shots  to  a 
minute  (about  four  guns  to  a  ship),  are  the  best. protection.  These 
shots  are  explosive  and  are  all  that  is  necessary  to  drive  the 
submarine  below  the  surface  and  keep  it  submerged.  A  submerged 
submarine  is  operating  at  a  great  disadvantage,  because  of  the 
three-fold  difficulty  of  limited  vision,  slower  speed,  and  much 
greater  difficulty  in  maneuvering.

discover  and  follow  submarines  when  they  aro  25  fathoms 
deep  at  Gibraltar.  One  method  of  destroying  submarines 
is  by  supplying  a  number  of  ships  with  mines  which  they 
tow  at  a  depth.,  of  about  60  fathomB.  When  a  patrol  or 
airplane  discovers  a  hostile  submarine  theso  ships  are 
summoned.  They  cluster  around  the  vicinity  where  the 
submarine  was  Been  to  submerge  and  explode  their  mlnoB. 

Ho  groat  success  has  been  claimed  yet  for  this  scheme. 

Another  method  now  quite  largely  used,  is  the 
towing  of  a  large  net  by  two  trawlers.  Various  attachments 
have  been  tried  out  on  theso  nets  - 

1.  Minos  have  boon  fastenod  at  intervals  along  the  net 
which  can  be  explodod  by  tho  trawlers  in  case  they  net  a 
submarine . 

2.  Calcium  flares  aro  secured  to  the  net  so  that  they 
float  on  the  surface.  In  oase  of  netting  a  submarine,  the 
flares  are  submerged  and  the  contact  with  tho  water  sets 
off  the  flares  as  warning  to  the  trawlers.

there  wore  periodB  when  for  four  months  at  a  time  no 
German  submarine  was  captured  by  any  British  Haval  Unit. 

This  was  said  to  be  due  to  the  use  by  the  Gormans 
of  a  hydrophone  which  consisted  of  some  sonoitive  form  of 
microphone.  By  this  instrument  they  wore  givon  plenty  of 
warning  to  submerge.

started  a  training  school  for  the  "listeners".  Blind 
mon  have  boon  found  to  be  25*  more  efficient  for  this 
service  than  normal  men.  All  crews  now  have  two  or  three 
expert  listeners  to  take  shifts  at  the  microphones.  After 
some  experience  the  listeners  can  determine  the  direction 
of  a  ship  within  2  points  of  the  compass.  They  can  also 
learn  to  distinguish  the  various  kinds  of  vessels  by  the 
sounds. 

As  to  range  of  these  microphones,  England  claims 
B  to  8  miles.  Italy  obtains  results  up  to  8  miles.  The 
French  can  detect  a  submarine  at  10  Km.  when  the  boat

Mo.  6932  Protection  of  Ships  against  Torpedoes.. 

Captain  Karl  Oscar  Leon,  Swfedish  Havy,  Stockholm, 
has  taken  out  patents  oh, a  method  of  protection  against 
torpedoes  consisting  of  the  firing  of  a  counter  charge 
from  submerged  tubes  to  meet  the  torpedo.  Captain  Leon 
states  that  his  experiments  show  that  with  100  Kg  of  gun¬ 
cotton,  ho  could  render  harmless  a  torpodo  anywhere  within 
26  meters  of  tho  explosion.  The  torpedo  either  being  de¬ 
tonated  or  else  caused  to  run  wild  by  deBtruotion  of  the 
mechanism. 

The  method  is  as  follows:-  Three  or  four  ejecting 
tubes  are  arranged  at  intervals  along  the  sides  of  tho 
ship.  These  tubes  are  equipped  with  means  of  firing  out 
explosive  charges  to  a  distance  of  about  100  meters  from 
the  ship.  Tho  tubes  ore  situated  near  enough  togother  so 
that  the  spheres  of  destructive  action  of  tho  explosives 
intersect.  In  this  way  a  torpodo  approaching  the  chip  can¬ 
not  roach  tho  ship  without  passing  through  the  ooncussion 
zone  at  some  point.  The  efficacy  of  this  plan  depends 
mainly  on  the  proper  timing  of  tho  counter  explosives. 

This  can  be  done  by  an  observer  who  when  he  sees  a  torpedo 
about  200  maters  from  tho  boat  immediately  starts  the 
counter  charges.  These  charges  have  time  fuses  which  de¬ 
tonate  them  when  they  are  76  to  100  meters  from  the  boat, 
or  at  about  tho  distance  whero  they  meet  the  approaching 
torpedo.  If  the  torpedo  is  not  Itself  destroyed,  it  is 
at  any  rate,  brought  to  the  surfaoe  by  the  effect  of  the 
explosion  on  tho  hydrostatic  piston.

My  dear  Mr.  Edison: 

X  thank  you  for  your  letter  of  the  16th  and  I  shall 
admonish  everybody  here  to  refrain  from  discussing  your 
work.  I  do  not  understand  how  anyone  learned  of  the  num¬ 
ber  of  reports  you  had  submitted.  They  are  carefully 
guarded  here,  and  further  than  the  statements  I  have  myself 
made,  which  were  general  and  to  the  effect  that  you  had 
been  giving  practically  your  whole  time  and  attention  since 
the  Government’s  separation  of  diplomatic  relations  with 
Germany,  nothing  has  been  said  in  this  office.  But  "a

Hon.  Thomas  A.  Edison,

Friend  Edison: 

X  have  been  working 'f5l“-ye*rS''in  ir.y  Harrisburg  laboratory  ( 
elimination  or  absorption  of  various  gases,  including  chlorine,  car¬ 


bon  dioxide,  carbon  monoxide,  sulphuretted  hydrogen,  hydrogen,  arsen- 
ine,  and  others,  and  can  control  them  completely  with  very  little  ex¬ 
pense. 

In  this  connection  I  can  take  your  batteries  (made  for  subma¬ 
rines!  and  utilize  them  in  such  a  way  that  a  submarine  can  be  pro¬ 
pelled  through  the  water,  at  surface  or  submerged,  over  thirty  knots 
an  hour. 

Are  you  interested?  If  so,  come  to  Harrisburg  next  Saturday,  the 
24th,  and  I  will  show  you  what  we  can  do  in  the  way  of  absorbing  the 
first  three  gases  mentioned  in  this  letter. 

I  hope  you  are  well,  prosperous,  and  happy. 

Faithfully  yours,

elaer  Polytechnic  Institute  to  assist  Ur.- 
Edison  remained  hero  one  day.-  Unfortunately 
it  happened  on  tho  .day.  of  his  arrival  tint 
Ur.  Edison  was  busily  ongagod  with  one  thing 
and  another  and  could  riot  give  Ur.  Ilowcomb 
any  problems  to  work  on  until  the  afternoon. 

He  worked  on  a-  certain  problem  for  a  few  hours 
in  the  afternoon,-  but  did  not  return!  by  the 
next  morning.  ,  V,o  got  a  letter  from  him  on 
the  day  af tor  that  stating  that  it  looked  to 
him  as  if  ho  were  wasting  t.irao ,  and. ho  did 
not  think  ho  could  afford  to  negloct  his 
College  work.  He  .therofore  excused  himself 
from  furthor  cervico. 

Of  com  so,  that  was  hie  privilogo, . 
and  I  EBay,. nay,  for  your  information,  that  Ur .

ing  next,  the  39th  instant,  at  ten  o‘clook. 

The  object  of  the  meeting  is  to  consider  the 
following  important  matters. 


Mr.  Albert  H.  Emery,  of  Glenbrook,  Conneotiout 
will  be  present,  and  will  explain,  with  drawings,  his 
method  of  treating  gun  barrels  in  the  manner  proposed 
by  Professor  Bridgman.  Mr.  Emery  has  carried  the  mat- 
ter  m uoh  further  forward  than  Professor  Bridgman, and  in 
view  of  the  action  taken  by  the  Committee  on  Ordnanoe 
and  Explosives  in  the  Bridgman  matter,  it  is  of  espeoial 
importance  that  the  method  of  Mr.  Emery  be  examined  and 
considered. 


Also,  Professor  Howe  will  be  present  and  will 
exhibit,  under  the  miorosoope,  some  slides  that  he  has 
made  showing  the  effeot  of  erosion  in  guns. 

Other  important  matters  will  also  be  brought 
before  the  meeting. 


For  these  reasons  I  should  be  very  glad  to 
have  you  attend  the  meeting,  although  you  are  not  a  mem¬ 
ber  of  the  Committee  on  Ordnanoe  and  Explosives.

NEW  YORK  uar oh  27,  1917. 

MH.  THOMAS  A.  EDISON, 

Thomas  A.  Edison,  Incorporated, 

West  Orange,  New  Jersey. 

My  dear  Mr.  Edison; 

Mr.  Meadowcroft  telephoned  your  message  about  a 
research  man  to  me  yesterday  and  I  had  Mr.  COlpittB  send  a 
couple  of  men  out  to  you.  Unfortunately,  M.r.  Mathes,  who 
has  been  out  on  previous  work,  is  away  from  the  city  for  a 
few  days  and  so  could  not  handle  the  work.  It  may  be  that 
either  you  or  we  will  wish  to  substitute  him  for  the  man 
who  is  now  with  you  as  soon  as  he  (Mathes)  returns. 

As  you  know  from  our  previous  conversation,  we 
are  anxious  to  do  whatever  we  can  to  assist  you  in  this  work 
for  the  Navy.  At  the  same  time,  as  I  explained  to  Mr. Meadowcroft 
yesterday,  we  ourselves  have  so  much  research  work  on  in  con¬ 
nection  with  specific  requests  from  the  Army  and  Navy  that  it 
is  very  difficult  for  us  to  spare  any  men  at  this  time.  These 
requests  are  piling  in  on  us  in  a  way  that  threatens  to  be 
embarrassing  and  I  sincerely  trust  that  you  will  be  able  to 
release  both  Mr.  aoriven  or  Mr.  Mathes  and  Mr.  Gargan  at  an 
early  date. 


-2- 


V/hile  I  do  not,  of  oourue,  know  the  exact  nature 
of  the  problem  on  whioh  you  are  working,  It  oooure  to  me 
that  posBibly  eome  of  the  things  on  whioh  you  think  our 
people  oould  he  of  help  might  be  handled  by  them  more 
advantageously  in  our  own  laboratories,  where  the  men  know 
the  ropes  and  have  all  the  facilities,  than  where  they  are 
attempting  to  do  things  under  a  more  or  lese  strange  environ¬ 
ment.  If  such  an  arrangement  is  feasible,  we  can  of  course 
keep  things  absolutely  confidential . 

With  kindest  personal  regardB,  I  am, 

yours  very  Binoerely, 


Chief  Engineer.

Dear  Mr.  Edison: 

In  regard  to  the  detail  of  an  officer 
at  your  laboratory  to  furnish  information  on  naval 
matters,  I  regret  very  muoh  that  I  cannot  find  one 
of  sufficiently  wide  experience  to  cover  all  the  sub¬ 
jects  on  which  you  work. 

In  thinking  this  over  I  have  come  to  the 
conclusion  that  it  is  better  to  have  you  phone  in  to 
the  Commandant's  Office  at  the  Navy  Yard  stating  the 
subject  you  want  to  discuss,  and  an  officer  who  has 
the  latest  information  on  that  subject  will  be  Bent 
out  at  once  to  your  laboratory.  Since  it  is  impos¬ 
sible  for  any  one  officer  to  keep  up  on  all  subjects, 
I  think  that  this  is  the  better  plan .  $  Ityo  *^rvt  lA^JP

3,iy  dear  Dr.  Jewett: 

Replying  to  your  favor  of  the 
£7th  instant,  let  me  say  I  was  trying  to  render 
unnecessary  the  presence  of  your  expert  on  the 
audion  by  compelling  my  own  men  to  work  it  out 
themselves  so  they  would  certainly  he  well  trained 
but  was  compelled  to  ask  for  your  assistance. 


handle  the  problem. 


As  to  Ur.  Gargan,  I  hope  to  send  him 
back  in  a  few  days.  It  is  scarcely  necessary 
for  me  to  say  that  the  assistance  you  have  so  kindly 
and  promptly  rendered ,  as  to  both  men  and  apparatus , 
is  very  greatly  appreciated,  and  if  any  inconven¬ 
ience  to  you  has  resulted  it  is  to  be  regretted. 
However,  it  is  all  for  Old  Glory! 

Yours  very  truly,

tion  59  act  of  June  3,  1916  entitled  "An  act  for  making  a 
further  and  more  effective  provision  for  the  National  Defense

My  dear  Mr.  Edison 

Thank  you  for  your  letter  of  March  29th 
enclosing  copies  of  your  range  finder. 

On  the  same  day  I  received  a  letter  from 
Ur.  Richards,  which  I  enclose  herewith,  giving  a  con¬ 
siderable  amount  .of  data  on  work  done  by  Mr.  A.  T.  Cole 
on  this  same  subject,  which  I  am  sending  for  your  infor¬ 
mation. 

You  will  note  that  in  this  latter  case 
work  has  been  done  with  the  Oscillograph  and  the  Tele- 
graphone,  as  well  as  the  phonograph,  and  I  thought 
this  might  be  of  special  interest  to  you  in  connection 
with  your  work  at  the  present  time. 

Veiy  truly  yours.

Dear  Sir 


The  people  of  Maryland  are  much  interested 
in  the  location  of  the  Naval  Laboratory.  The 

information  coming  from  Washington  that  the  committee, 
havIBgthe  selection  of  the  site  in  charge,  is  unanimous, 
With  the  exception  of  yourself, for  Annapolis,  has 
aroused  much  interest  here. 


The  people  here  would  greatly  appreciate  it  if 
they  could  learn  the  basis  of  the  objection  to  Annapolis. 

Of  course,  native  pride  leads  them,  perhaps, 
to  exaggerated  ideas  of  the  advantages  of  Annapolis  for 
this  site.  %t  they  are  very  anxious  to  do  what  they 
can  to  present  its  claims  in  every  possible  way. 


Yours  very  truly. 


C.  M.  HARWOOD!

e  a  young  man  working  for 


e  name  of 

.  Cox  who  is  an  expert  chemist.  He  has  done  a  lot  of  work  in  org¬ 
anic  chemistry  as  well  as  in  silicate  chemistry.  He  is  at  the  present 
time  working  on  developing  our  optical  glass  processes  with  the  view 
of  getting  this  material  out  in  much  larger  quantities  than  at  present. 

He  was  in  ray  office  this  morning  and  was  very  restive  and  is 
figuring  on  going  hack  to  Kentucky  to  enlist  at  his  home  town.  X  have 
told  him  that  the  work  he  is  doing  at  the  present  time  is  much  more 
important  to  the  U.  S.  Government  than  anything  which  he  could  do  in  any 
other  department  and  in  reply  he  said  he  did  not  care  what  he  did,  so 
long  as  he  was  of  use  to  his  country,  but  he  would  like  to  be  detailed  to 
some  work  that  would  have  to  do  with  the  preparedness  of  the  U.  S.  in  the 
coming  conflict. 

If  there  is  any  place  where  you  think  he  would  be  more  useful 
than  at  his  present  work,  if  you  will  advise  me,  I  will  put  him  in  touch 
with  you,  but  if  you  consider  that  his  work  in  connection  with  optical 
glass  is  a  thing  which  he  should  follow,  I  would  greatly  appreciate  it 
if  you  would  write  me  to  that  effect  or  have  him  definitely  assigned  to 
this  work.  I  think  it  would  be  a  great  mistake  for  him  to  go  into  the 
ranks  but  at  the  same  time  be  will  not  stay  in  the  industries  unless  he 
is  definitely  assigned  there. 


I  am  still  waiting  for  the  dimensions  of  the  optical  glass  which 
you  require,  together  with  the  index  of  refraction  and  X  shall  be  very 

glad  to  furnish  you  with  the  same  a-  “ - -  T  ’•«'.«1ve  the  dimensions

I  have  noted  your  letter  of  the  6th  with 
reference  to  samples  of  carbonized  seeds  and  globular 
carbon.  As  regards  globular  carbon,  we  sent  you  about 
the  middle  of  February  on  your  order  #52234  four  lots 
of  four  ounces  each  .025,  .030,  .035  and  .040"  diameter. 
These  represent  the  principal  sizes  in  common  U3e 
although  we  can  make  the  carbon  a  little  larger  and 
a  little  smaller  in  diameter.  Vie  shall  be  pleased  to 
have  our  factory  send  you  a  complete  sat  of  samples 
of  our  Columbia  Globular  Carbon  in  various  sizes  as 
follows: — 

.030,  .025,  .030,  .035-,  .040,  ,045  and  .050"  diameter 

These  will  be  tagged  indicating  size  in  each  case  and 
we  trust  will  be  of  assistance  in  connection  with  your

Dear  Mr.  Edison:- 

I  understand  from  Mrs.  Chubb  that  you  were  inquir¬ 
ing  whether  you  could  have  use  of  my  boat  for  some  of  your  experi¬ 
ments  in  Newark  Bay. 

The  only  boat  whioh  1  have  is  the  "SATELLITE*  tthioh  is  a  40  ft. 
power  boat  with  a  50/75  h.p.  engine.  She  is  at  present  out  of 
commission  and  it  will  probably  take  five  or  six  days  to  put  her 
in  condition  to  be  used. 

I  would  be  glad  to  let  you  have  her  were  it  not  for  the  fact  that 
I  have  offered  her  to  the  Government  and  have  been  advised  by  them 
that  they  will  accept  her.  So  far  they  have  taken  no  steps  beyond 
giving  me  this  advioe  but  I  feel  she  is  pledged  to  them. 

If  this  boat  is  just  what  you  want  and  you  so  desire  I  will  be 
glad  to  take  it  up  with  the  Naval  Authorities  and  s»e  if  they  will 
release  her  for  this  special  service.

HP..  THOMAS  A.  EDISON,  s/  'j 

Orange,  / 

New  Jersey, 

My  dear  Mr.  Edison: 

Replying  to  your  letter  of  April  13th  about  the 
co-operation  between  Fessenden  and  the  General  Eleotrio 
Company* s  Research  Department  on  submarine  deteotion,  I  feel 
perfectly  safe  in  assuring  you  that  the  General  Electric 
Company's  vacuum  tube  (audion)  detector  and  amplifier  is  not 
superior  to  those  which  we  make.  Whether  they  know  better 
than  we  how  to  employ  this  devioe  in  connection  with  sub¬ 
marine  deteotion  I  cannot  say  as  I  have  no  first-hand  know¬ 
ledge  of  Just  what  Fessenden  is  doing. 

The  vacuum  tube  amplifier  is  BUoh  a  remarkable 
instrument  that  its  possibilities  in  connection  with  sub¬ 
marine  detection  are  great.  From  the  standpoint  of  the 
country  I  hope  earnestly  that  some  of  them  may  prove  success¬ 
ful.  At  the  same  time  I  should  feel  not  a  little  ohagrined 
if  the  successful  method  should  be  found  to  be  one  whioh 
indicated  lack  of  skill  and  insight  on  our  part. 

YourB  very  truly,' 

Chief  Engineer.

Gentlemen:  (Attention  of  Mr.  Meadowcroft)  / 

Your  favor  of  the  14th  has  been  handed  to  me  for  reply 
for  the  reason  that  we  are  really  so  filled  up  wijrh  orders  and 
contracts  that  v/e  find  it  almost  impossible  to  t*Ske  on  more,  with 
any  degree  of  certainty  as  to  delivery.  y 

When,  however,  we  have  a  request  from  Mr .  Edison, 
and  especially  so  to  help  him  out,  and  to  yrto  our  little  hit  for 
our  own  Government,  it  opens  up  another  train  of  thought,  and  we 
will  put  other  work  aside  as  an  accommodation,  first  to  our 
Government,  as  I  say,  and  then  to  our  did  friend,  Mr.  Edison, 

The  price  will  he,  for  the  steel  tubes  specified, 

16/  per  foot  net,  and  by  special  effort  we  believe  we  con  mike 
shipment  to  you  within  two  to  three  weeks  from  receint  of  order.  It 
would  be  well  for  you 
stiff  and  rigid,  or  so

Edison's  signature  1b  so  very  faint, that  we  can  hardly  read  it. 
He  evidently  blotted  it  quickly.  The  thought  occurred  to  me 
that  you  would  be  willing  to  have  a  copy  made  of  this  letter  if 
I  sent  it  to  you,  and  have  Mr.  Edison  sign  it  with  good  black 
ink.  Will  you  do  it?

Dear  Sir: 

I  have  referred  your  letter  of  April  14th 
in  rogara  to  the  Yale  heliometer  to  M.  E.  Smith,  the  astron¬ 
omer  in  charge  of  the  observatory,  who  will  communicate  with 
you  on  the  subject. 

I  think  it  it  quite  doubtful  whether  the 
heliometer  can  be  used  for  the  nurpose  you  mention  since  it 
iB  in  reality  a  doiible  image  micrometer  and  is  not  suitable 
for  any  use  similar  to  that  of  a  theodolite.  It  is  very 
large  and  heavy  and  it  would  be  necessary  to  take  down  the 
walls  of  the  dome  in  order  to  get  it  out  us  they  are  built 
around  the  instrument.

Dear  Sirs 

Your  recent  favor  has  been  received.  V/o  beg 
to  say  that  Ur.  Adison  is  working  night  and  day  for  tho 
Government  and  cannot  possibly  spare  the  time  to  personally 
examine  suggestions  or  inventions  offered  in  connection  with 
matters  of  National  Defense.  He  does  not  even  see  his  regular 
mail  for  sometimes  a  week  at  a  time. 

He  has,  therefore,  directed  that  communications 
of  this  kind  be  returned  to  tho  writers,  with  the  suggestion 
that  they  communicate  direct  with  Ur.  Thomas  HobinB,  secretary 
of  tho  liaval  Consulting  Hoard,  13  Park  How,  Hew  fork  City. 

Ur.  jdison  has  not  had  time  to  look  at  your 
communication,  and  wo  return  it  herewith. 

Yours  very  truly.

Dear  Sin- 


.Hrofessor  Bumstead  of  the  Sheffield  Scientific 
School  has  forwarded  to  me  your  inquiry  of  the  I4th 
relative  to  the  Yale  Heliometer. 


It  seems  to  me  that  you  are  looking  for  a 
povtaol.e  iiistruinen^  of  some  sort  and  do  not  realize  that 
our  telescope  is  passive  affair  that  could  not  be.  easily 
moved  about  over  a  ease  line  of  from  three  to  six 
hundred  fe«t  as  mentioned  in  your  letter.  The  base  line 
which  we  us«  is  I8b, 000,000  miles  long  and  the  success  of 
our  measure®  depends  upon  the  careful  avoidance  o'  of  all 
jars  and  disturbances  during  the  six  months  that  it  takes 
the  earth  to  earrl  us  that  distance. 


At  the  time  of  its  erection  in  188 l  a  solid 
masonry  pi’er  having  a  diameter  of  twelve  feet  was  first 
built  from  heri  roek  to  a  height  of  forty  feet,  a  circular 
oriel:  lower  was  then  put  up  around  the  pier  to  the  upper 
floor  level  and  after  the  telescope  vtas  hoisted  into  place 
the  tower  was  completed  and  capped  by  a  revolving  dome. 
Therefore  the  only  way  to  get  the  telescope  out  would  be 
to  demolis.il  the  building,  which  hardly  seems  practicable. 


Very  truly  youri 

Pr<gr. 

Astronomer  in  Charge.-

Hr.  Thomas  A.  Edison, 

Orange,  N.J. 

Pear  Sir: 

Replying  to  your  letter  of  April  18th,  I  con¬ 
sulted  Pr.  W.  L.  Elkin  (formerly  director  of  our  observatory, 
now  retired}  with  regard  to  the  existence  of  small  heliometers 
in  this  country.  He  informs  me  that  there  are  no  small  astro¬ 
nomical  heliometers  in  this  country  and  only  a  few  in  the 
world  -  two  or  three  in  Germany,  one  in  Scotland,  and  two  in 
Russia.  He  suggested,  however,  that  you  might  possibly  ac¬ 
complish  your  purpose  by  using  the  principle  of  the  Helmholtz 
opthalmoscope ,  in  which,  however,  the  two  rotating  plates  of 
glass  would  be  put  in  the  converging  beam.  He  thought  an 
ordinary  telescope  could  bo  modified  in  this  way  fairly  easily. 

If  you  should  think  of  trying  an  arrangement 
of  this  kind  Pr.  Elkin  could  doubtless  give  you  useful  advice. 
His  address  is  206  Pivingston  Street. 

I  afterwards  talked  to  Professor  C.  S.  Hastings 
upon  the  subject.  He  informed  me  that  the  John  A.  Brashear 
Company  of  Pittsburgh  had  made,  and  he  thought  still  had  in 
their  possession,  some  small  telescopes  with  split  objectives 
to  be  used  in  the  same  way  as  a  heliometer.  If  his  memory 
is  not  at  fault,  they  have  an  aperture  of  about  two  inches 
and  angles  of  about  1/20-th  of  a  second  can  be  measured  by  them. 
Although  those  ore  smaller  instruments  than  you  are  looking 
for,  it  might  be  that  hhey  would  at  least  serve  for  your  pre- 


liminary  experiments.  I  have  no  doubt  that  Brashoar 
could  make  a  larger  instrument  of  thin  type  if  you  desired.

'He  have  your  two  letters  of  the  18th  and  take  pleasure  in  re- 
j  follows. 

First,  in  regard  to  the  Huygonian  eye  piece  of  2"  equivalent 
focus,  we  ora  fortunate  in  having  several  Bets  of  lenses  for  this  focus 
and  one  of  our  men  is  at  work  mounting  it  as  I  write.  As  this  is  one  of 
oar  special  wide  field  eye  pieces  it  will  he  larger  in  diameter  than  the 
'ordinary  eye  piece,  and  from  the  fact  that  your  objective  is  of  short  foc¬ 
us  we  presume  it  is  just  what  you  want.  We  do  not  however  quite  understand 
)  hut  we  think  the  constants  will  he  as 


the  words  (Biameter  eye  stop,  ±yor» 

you  wish  them  as  we  have  staWrds  after  long  experience.  If  you  find 
you  oan  get  your  focus  without  a  draw  tube  ubo  only  the  eye  piece,  hut  we 
are  providing  a  6"  draw  tube  Ifor  use  if  the  eye  piece  focus  comes  too  far 
out  in  your  telescope. 

Secondly,  as  to  th^H^Wter' \he'Vn^  thing  we  have  here  is 
a  Fiske  Eange  Finder,  which  has  a  divided  objective  of  4  inches  diameter 
,  and  30  inohes  focus.  If  the  range  finder  was  not  so  heavy,  it  might  serve 
"Mr  Edison  purpose.  The  range  finder  was  constructed  to  measure  ship  dis¬ 
tances  from  a  double  image  of  the  mast.  The  weight  is  about  40  pounds. 

We  will  send  drawings  of  it  if  you  like,  or  we  will  loan  Mr  Edison  the 
objective,  which  is  a  fine  one  and  a  suitable  eye  piece,  either  erecting

or  inverting  or  both  and  he  can  mount  it  to  suit  his  wishes.  Write  us 
and  we  will  do  our  best  to  accomodate  you.  The  eye  piece  will  be  raddy 
this  evening. 

Pray  give  my  personal  and  best  wishes  to  my  friend  of  many 
years.  Tell  him  his  nearly  77  year  old  friend  has  3ust  returned  from  a 
five  months  tour  of  the  Orient  and  still  lives.

Secretary  Baker  advises  me  that  a  month’s  leave  of  absence 
has  been  granted.  I  am  pointing  out  to  him  that  your  re¬ 
quest  was  that  he  be  released. 

I  trust  that,  in  view  of  the  importance  of  his 
own  and  the  character  of  the  work  you  are  performing  for 
the  Government,  that  this  can  be  accomplished  before  his 
leave  of  absence  expires.

Dear  Mr  Edison  , 

While  here  temporarily  on  a  professional,

the  patentee  of  an  airship  .  He  has  patents  from  our  government 
Germany  Prance  and  England  . 

He  claims  to  have  made  flights  with  his  machine  before 
Curtis  or  the  Bright  machines  were  known  .  and  from  a  long  con 
ference  I  had  with  hinu.l  am.icbnvincednt  ,  that  all  he  claims 
is  true  . 

I  subjected  him  to  a  rigorous  examination  and 
asked  him  to  give  me  a  detailed  writing  of  history  and  descrip 
tion  which  he  did  and  copy  of  same  is  enclosed  herewith  ,  I 
having  the  original  . 

Should  you  look  upon  his  invention  with  favor  ,  and 
will  send  transportation  and  expenses  ,  for  him  and  myself  , 

I  shall  be  glad  to  go  to  Washington  with  him  ,  that  you  may 
have  him  superintend  the  construction  of  a  machine  . 
tie  advised  me  he  would  go  .  If  all  he  claims  be  true  ,  the 
government  should  construct  an  experimental  machine  .

Thomas  A.  Edison, Esq. ,, 
Menlo  T’ark.N.  J. 


Dear  Mr.  Edison:- 

1  have  to-day  received  from  a  distant  cousin  of  mine 
residing  in  Montana  a  sketch  which  1  enclose  herewith 
concerning  which  Mr.  Norris  writes  ir.  part  as  follows: - 


"ITy  plan  would  he, with  a  system  of  outriggers, 
or  perhaps  davits, to  control  theposition  of  the 
device, to  virtually  surround  a  ship  with  a  hoom 
of  spars, with  plain  or  corrugated  sheet  steel, 
depending  from  them  to  a  suitable  depth, so  as  to 
intercept  and  explode, at  some  distance  from  the 
ship, torpedoes  sent  from  nearly  all  directions. 

As  1  understand  it, the  nets  once  used  by  bavtlesnips 
could  be  used  only  with  the  ship  at  rest, owing  to 
tlie  great  friction  when  in  motion, and  that  torpedoes 
now  can  he  provided  -with  nutting  edges  at  the  nose, 
so  that  the  nets  do  not  adford  adequate  protection 
even  when  tire  ship  is  at  rest. 

"With  these  spars  moving  in  single  file, the 
interference  with  the  ships'  speed  would  he 
practically  negligible .and  with  controlling  supports 
at  suitable  intervals, the  ship  could  manoeuvre 
without  interference  from  them. 

"The  sheet  steel  could  be  fastened  to  the  spars 
rigidly, or  perhaps  loosely, to  give  greater 


flexibility." 


"Ralph  V.  Norris."

My  dear  friend  Edison:- 

It  was  a  delight  to  see  your  signature  to  a  letter. 

It  is  thirty  years  since  you  wrote  me  the  first  time,  wanting 
me  to  come  and  take  charge  of  a  shop  for  the  making  of  physi¬ 
cal  apparatus,  and  when  I  told  you  I  wanted  to  stick  to  my 
hobby  if  I  had  to  be  laid  away  in  a  pauper's--  what  do  you 
call  it?  --  you  wrote  me  "You  talk  like  a  philosopher'',- the 

si**? 

first  time^  the  last  time  I  was  called  a  philosopher  until  the 
darned  Ohinese  got  hold  of  me. 

.Veil,  aside  from  this  pleasantry,  I  write  to  say  we 
are  packing  the  Eiske  instrument  for  you.  fhought  we  could 
get  it  off  to-day,  but  ^I_  had  to  make  some  sort  of  a  box  for 
it,  and  we'll  get  it  off  in  the  A.  K. 

Admiral  Eiske  made  several  changes  in  it,  and  I  think 
it  would  have  been  adopted  but  the  secondary  image  never  was  quite 
satisfactory. 

It  has  been  a  pretty  costly  instrument,  and  like  ever  so 
many  other  experimental  instruments  we  have  made  for  "the  other 
fellow",  we  are  left  in  the  hole  on  the  cash  side,  but  then  astro¬ 
nomical  instrument  makers  are  all  supposed  to  get  to  heaven  and 
get  their  pay  there.  As  to  electricians*,  ^hop^ou^hav^ heard 
the  story  told  at  the  Electrical  Club  of  London/;  If  you  haven't, 


.-2- 


.1  will  tell  you  when  I  see  you;  it's  too  wicked  to  tell  by  lette 
We  are  sending  you  the  enclosed  description  of  R.  E.  E • 
and  I  will  have  you  a  set  of  blue  prints  made  at  once. 

If  you  want  to  take  it  apart  and  use  the  objective  eye-

Dear  Hr.  Coffin: 


I  learn  from  the  Hunition  rankers 
near  me  that  our  Government  1b  about  to  adopt  a 
9. {3  shell  instead  of  9.2  shell,  while  everybody 
in  the  United  States  is  rigged  up  for  9.2.  Che 
delay  in  this  change  would  bo  months. 

-  One  of  the  Haters  was  at  Washington 
5  days  asking  what  slabs  would  be  adopted  and 
finally,  after  being. aont  to  5  difforont  Bureaus, 
or  men,  the  last '.man  said  9.6. 

Che  Hunitions  maker  said  "Everybody 
is  rigged  up  for  9.2",  but  the  Bureau  man  said, 
"that  don’t  matter  we  think  9.5  is  hotter". 

.  Chore  may  be  some  good  reason,  but  it 
looks  strange  to  a ’layman. 

yours  vory  truly.

Have  a  series  of  collapsed  parafined  canvas 
hags  attached  along  both  sides  of  a  ship  above  the 
water  line. 

These  will  be  like  the  links  of  a  chain  of 
sausages,  and  will  extend  from  the  how  to  the  stern. 
Each  hag  can  be  connected  by  a  chain  passing  under  the 
keel  to  the  corresponding  bag  on  the  opposite  side,  or 
each  bag  can  be  placed  under  a  projecting  wing  of 
steel  riveted  to  the  sides  of  the  ship. 

To  prevent  the  ship  from  sinking,  compressed 
air  can  be  forced  through  a  relatively  large  pipe 
from  a  tank  of  compressed  air  on  ship-hoard. ;  this 
will  cause  the  bags  to  baloon  and  the  ehip  thus 
supported  by  the  inflated  bags  might  be  kept  afloat. 

Or  steel  tank3  might  be  attached  a  few 
feet  below  the  'line  of  the  loweet  deck  and  the 
ship  could  be  supported  by  them  after  it  had  3unk 
to  thie  level.

ay  dear  Friend: 

Heplyine  to  your  letter  of  March  23.  I  take  pleasure  in  replying 
that  I  now  can  take  ears  of  all  the  gases  generated  in  submarines ,  and 
at  very  low  cost. 

Also,  the  gases  or  fumes  from  Diesel  engines. 

The  chemical  compound  that  I  have  devised  will  absorb  or  elimi¬ 


nate  them  all;  and  two  of  the  gases  can  be  utilised,  making  a  calor¬ 
ic  power  nearly  double  that  of  gasoline,  toward  the  propelling  of  the 
submarine  to  more  than  thirty  knots  per  hour. 

There  are  only  two  persons  in  the  world  that  know  the  formula, 
one  of  my  assistants  and  myself. 

I  have  inspected  a  number  of  submarines,  and  know  what  I  am 

writing  about. 

Wishing  you  success  in  all  your  endeavors,  I  remain 
Faithfully  yours, 


Edison  Portland  Cement  Co. 


STEWARTSVILLE,  N.J. 


Ur.  Thomas  A.  Edison,

Dear  Ur.  Edison: - 

I  note  your  comments  as  to  the  concrete 
ship  proposition,  and  I  am  today  in  receipt  of  a  letter  from 
Ur.  E.  Huntington  Clark,  Chief  Engr.  of  the  U.  S.  Shipping 
Board,  Washington,  D.  C.,  which  reads  as  follows :- 


"Many  thanks  for  the  information  contained  in 
yours  of  the  30th,  regarding  the  concrete  for  vessels 
and  you  may  rest  assured  that  the  problem  will  receive 
earnest  consideration.  ..  ,  . 

We  must  confess  that  we  feel  a  little  timid  about 
such  a  radical  departure  from  standard  methods  of  ship 
construction  at  this  time  on  large  scale.  At  the  same 
time,  we  must  admit  that  the  arguments  in  favor  of 
concrete  construction  are  of  sufficient  force  to 
justify  thorough  investigation." 


I  am  having  Ur^JEtercy.  H.  ^Wilson.,  who  has 
had  considerable  experj.enoe--bo'th"in  ship-building  and^also 
in  concrete  construction,  prepare  a  report  as  to  the  feasi¬ 
bility  of  the^i'dea,  which  X  expect  to  send  to  Mr.  Clark  <ln 
the  c  ourself  a  fewdays. 

Wilson  is  collecting  information  as  to 
the .vibration  method  of  pouring  conorete.^and  toll  me  on 
Eiiday/last  that  by  this  method-,  plusS,*  double-  time  in 
U'i 4,1, Jk  he  felt', it  was  entirely  practical  to 


Yours  very  truly,

Mr.  W.H.  Meadowcroft: 

We  are  sending  by  Parcel 
Post  goggles  we  showed  you  this  morning, 
and  also  the  balanoe  of  blaok  goggles, 
on  whioh  we  have  fitted  the  new  bridge. 

This  bridge  is  not  as  strong 
as  it  would  be  in  the  finished  produot, 
as  it  was  Boldered  in  our  shop  and,  of 
oourse,  is  not  as  rigid  aB  would  be  required. 

We  have  also  fitted  the  headband  to  this 
goggle . 

We  feel  sure  this  will  be  -f- 
the  best  sample  yet  submitted,  as  -a>t=ts^^frvu<3^v-vv 
oan  be  controlled  so  as  not  to  be  unoom- 
fortable  to  the  wearer.  ‘  ■ 

The  felt  lined  goggle  is 
sent  so  that  Ur.  Edison  oan  see  how  it 
looks,  but  we  fear  that  it  wouldi  be  too 
heating  to  the  skin.  The  blaok  goggle  is 
especially  desirable,  as  it  is  the  deadest 
and  most  sanitary  goggle  of  the  entire  Xot. 

C;i.  5  Construction  is  the  simplest 

and,  in  our  opinion,  it  offers  advantages 
over  every  other  we  have  seen. 

We  would  be  glad  to  hear  your 

report.

/My  ^bar  Mr.  Edison:  ^ 


May  13,  1917. 


I  am  enclosing  a  letter  from  a  Mr.  Const'antine  which 
contains  a  suggestion  that  is  new  to  me  and  may  he  worth 
consideration.  His  scheme  is  to  have  a  vessel,  well  armed 
against  submarines,  and  with,  good  speed,  to  he  fitted  with 
some  apparatus  that  will  transmit  sounds  through  the  water 
simulating  the  pounding  engine  and  slowly  revolving  screw 
of  some  tramp  steamer.  If  a  submerged  submarine  hears 
this  sound  she  might  come  to  the  surface  to  attack  the 
supposed  tramp  and  get  an  unexpected  reception. 

I  am  just  sending  it  for  your  consideration. 


With  regards  and  best  wishes.

our  letter  of  Hay  15th  addressed  to  Commander  Upham 
showing  the  disposition  which  we  have  made  of  the 
matter. 


Commander  Upham  is  to  advise  us  as  to  the 
operation  of  the  device  during  the  cruise  and  as 
soon  as  we  hear  from  him  we  will  communicate  with 
you  again.

Boatswains  Mato  J.  Struth,  a  devioe  whioh  was  developed 
by  Mr.  Thomas  A.  Edison,  for  the  purpose  of  facilitating 
the  detection  of  porisoopeB  or  other  objects  at  sea  on

hoar  Sir ' 

She  writer  called  on  ilr.  lake  of  your 
How  York  office  laBt  Friday  in  r  oforoneo  t  o  a 
clock  which  ill*.  Hdison  will  require  in  connection 
with  somo  experimental  work  now  being  done  for 
the  United  Statoe  Havy  Department.  I.lr.  Lake  gave 
the  natter  very  careful  attontion,  but  on  account' 
of  the  technical  and  manufacturing  questions  involved, 
suggested  that  wo'  consult  you. 

to  explanation  of  our  requirements ,  wo 
hro  using  a  heavy  spring  motor  oloctricelly  self¬ 
winding,'  fo:  driving  a  heavily  loaded  dice.  She 
motor  speed  is  regulated  by:. a  centrifugal  govornor, 
but  this  regulation  whilo  cloco  is  not  sufficiently 
accurate  for  our  purpose  and  thorofore  wo  wich  to 
obtain  a  good  clock  movement  to  be  usod  as  a  corroc-  • 
five  moans .  - 

Our  plan  is  to  have  a  shaft  projecting 
from  the  clock  movomont  in  line  with  a  shaft  from 
the  motor  mechanism,  but  those  shafts  are  not  to 
'bo  connoetod.  Choy  are  to  run  at  approximately 
the  same  speod,  say  one  revolution  ppr  minute,  and 
a  very  light  contact  arm  on  the  clock  shaft  is  to 
make  oloctrieal  contacts  on  an  arm  attached  to  the. 
motor  shaft,  the  effect  of  which  is  to  either  haB ten 
or  rotard  tho  motor  speed  whenever  the  speed  of  the 
motor  shaft  varies  from  that  of  tho  clock.  Che  con¬ 
tacts  would  only  bo  made  when  tho  motor  stopped  out 
of  speed  a  certain  allowable  amount,  the  electrical 
imnulsos  thus  obtained  would  -  oporato  through  magneto  ; 
toeithor  lighten  or  increase  the  load  on  the  hall, 
govornor  and  thus  bring  the  motor  hack  in  step  with 
tho  clock. 


Shis  apparatus  is  to  he  used  6n  shipboard  and 
the  clock  must  therefore  bo  provided  with  a  lever 
oscapemont.  It  should  koop  time  to  within  6  seconds 
per  day  although  ovon  closer  regulation  is  desirable 
if  it  ccn  readily  be  obtained;  We  would  roquiro-  two 
such  movements  for  our  experimental  work. 

As  wo  wish  to  obtain  a  -clock  which  is  as  accur¬ 
ate  as  possible,  it  appoars  that  the  Waltham  eight-day 
box  Chronometer  might  bo  usod  for  the'  purpose  if  such 
a  controlling  shaft  could  bo  brought  out  or  the  rear 
of  the  movomont.  We  realize,  of  course,  that  there 
ma-»  bo  various  reasons  why  such  altorations  could  not 
be^mado  and  that  it  is  apt  to  causo  you  considerable 
trouble  to  make  up  two  movements,, in  this  way.  Howevor, 
in  view  of  the  importance  of  this  work,  we  feel  that 
we  can  count  on  your  cooperation  insofar  as  you  may 
bo  able. 

If  such  alterations  could  be  made,  wo  would  be 
glad  to  havo  you  quote  us  with  dolivory- promise  on 
'two  Chronometers  thus  alterod,  less  wood  caso,  or  wo  _ 
will  thankfully  reooivo  any  alternative  suggestions 
or  recommendations  you  might  make.  Wo  foel  that  you 
will  give  this  matter  prompt  attention  and. would  bo 
pleased. to  hear. from  you  at  an  early  dato.

Dear  Sir : 

Please  accept  my  thanks  for  the  interview  you  granted  me 
yesterday,  your  very  courteous  attention  to  what  I  had  to  say, 
the  interest  you  took  in  the  proposition,  and  for  your  letter  to 
Mr.  Coffin. 

I  am  leaving  here  the  end  of  this  week  to  spend  Sunday 
in  North  Carolina,  and  I  will  pass  through  Washington  on  my  return 
early  next  week.  If  Mr.  Coffin  should  care  to  see  me,  I  could 
stop  off  in  Washington  and  call  on  him  Monday  or  Tuesday,  the  28th 
or  29th. 

It  has  been  my  intention  to  offer  to  the  Government  my 
services  for  the  duration  of  the  war.  I  think  I  could  be  of  most 
service  in  connection  with  the  production  and  recovery  of  Toluol, 
Benzol  and  other  gas  products  useful  for  munitions,  and  I  thought 
of  enlisting  and  applying  for  a  commission  in  the  Department  of 
Engineers  and  asking  to  be  detailed  on  that  work. 

If  you  know  of  any  other  way  in  which  I  could  be  of  more 
seryice  during  this  national  emergency,  I  would  be  glad  to  have 
you  consider  me  at  the  disposition  of  your  Committee. 

I  am  46  years  old,  of  independent  means,  a  University 
graduate  ih  Electrical  and  Chemical  Engineering;  am  a  consulting 


engineer  by  profession,  retained  by  a  number  of  the  largest 
V.'aier  Gas,  Oxygen  and  Acetylene  companies  in  the  United  States; 
have  had  24  years'  experience  in  the  handling  of  men  and  in  the 
production  of  illuminating  gas,  calcium  carbide,  acetylene,  and 
oxygen  by  both  the  electrolytic  and  liquid  air  processes.  I  am  a 
member  of  most  of  the  scientific  societies  in  connection  with  the 
various  industries  mentioned,  and  have  a  very  wide  acquaintance 
among  the  personnel  of  the  various  Gas,  Carbide  and  Oxygen

My  dear  Mr.  Edison: 

I  have  the  pleasure  to  acknowledge  receipt  of  your  letter  of  May  21st, 
which  I  have  carefully  read.  In  reply,  I  will  say  that  we  have  had  up  with 
the  Committee  of  the  National  Electric  *ad=8SB-  Light  Association!  the  matter 
about  which  you  write,  and  they  have  placed  a  representative  down  here  to 
work  with  us  on  just  such  problems  as  this  which  may  come  up  from  time  to 
time,  in  connection  with  the  manufacture  of  munitions. 

While  it  does  not  seem  necessary  for  the  Engineer  of  the  Chicago  Gas 
Company  to  make  a  special  trip  here  at  this  time,  I  shall,  of  course,  be 
glad  to  have  him  call  to  see  mo  whenever  he  may  be  in  Washington.

Edison  Laboratory,  Attention  Mr.  John  Gargan. 

Orange,  N.J. 

Gentlemen:- 


Your  letter  of  May  Plst  la  received  and  contents  duly 
noted.  This  Company  will  be  glad  to  do  what  It  can  to  help  out  In 
the  experimental  work  which  you  are  doing  for  the  U.S.  Navy  Dept. 

We  are  sending  you  one  of  cur  8-Duy  movements.  This 
is  the  only  movement  which  we  make  which  we  believe  might  be  suit¬ 
able  for  your  purpose.  It  runs  eight  days,  as  its  name  implies, 
an'd  is  a  very  accurate  time  piece.  On  examining  the  movement  you 
will  note  thut  the  second  hend  shaft  revolves  once  per  minute, 
which  we  understand  is  the  speed  you  require  for  your  regulating 
device.  This  second  hand  shaft  can  be  lengthened,  within  reason¬ 
able  limits,  on  either  end,  depending  upon  the  direction  of  drive 
which  you  call  for.  The  power  of  this  movement  is  such  that  the 
shaft  of  the- second  hand  can  be  sc  lengthened  and  made  to  carry 
a  light  load,  but  you  oan  understand  that  the  load  must  be  light, 
otherwise  it  will  interfere  with  the  time-keeping  qualities  of 
the  movement. 


We  suggest  that  you  examine  this  movement  in  con¬ 
nection  with  what  you  want  to  do,  and  let  us  know  whether  or  not 
you  think  such  an  arrangement,  as  we  suggest  would  give  you  the 
drive  which  you  want.  If  this  scheme  appears  feasible  to  you, 
and  you  will  send  us  drawings  of  hew  you  wish  to  apply  it,  and  how 
much  cf  a  load  the  second  hand  shaft  will  he  required  to  carry,  we 
will  at  once  inform,  you- whether  in  our  opinion  it  is  practical  or 
not.  We  should  be  glad  to  sur.pl y.  you  as  soon  as  possible  with  the 
movements  fitted  in  this  manner  If  the  scheme  seems  t.o  bo  a  practi¬ 
cal  one.  Should  you  decide  that  the  second  hand  shaft  should  be 
lengthened  on  the  dial  side,  the  time  indicating  dial  could  be 
made  smaller  than  !the  -present  or.e,  which  we  believe  would  be 
satisfactory.  ' 


It  would  be  impossible,  owing  to  the  tine  required 
in  making  tools,  lack -of  skilled- labor,  etc.  for  us  to  get  up  a 
special  movement  for  this  purpose,  as  it  would  take  considerable 
time  to  build.  We  have,  however,  applied  this  P-Day  movement  on 
certain  regulating  devices,  like  the  thermostat,  and  find  they  can 
be  depended  upon  to  run  well  and  keep  close  to. time  if  carrying 
a  light  additional  load.  - 


Shall  be  glad  to  hear  from  you  qn  receipt  of  this 
letter  and  the  movement >  and  get  your  requirements  in  detail  form.

My  dear  Mr.  Meadowcroft:  ■ 

_  help  of  Mr.  Frank  Smith,  in  Seoretary 

Baniels  office,  I  am  trying  to  keep  a  correct  file 
of  Mr.  Edison's  letters  to  the  Secretary.  The  majority 
of  them  are  referred  to  my  office  for  action  hut  occa¬ 
sionally  one  goes  to  some  other  office  and  it  is  the 
longest  time  before  I  can  get  hold  of  it  and  see  that 


oon  3?^letter  to  1Sr'  Smith  you  referred  to  Eeport 
89C,  of  vmioh  I  have  no  copy.  I  do  not  know  where  to  lo¬ 
cate  it  and  29B.I  have  alright.  In  29B,  dated  May  16th. 
reference  is  made  to  the  Secretary's  letter  of  the  11th 
and  I  cannot  locate  a  copy  of  that. 

I  am  writing  to  ask  you  if  you  will  kindly  send  me 
a  carbon  of  eaah  letter  that  is  written  so  that  I  may 
know  where  to  look  for  it  and  trace  it  up.  I  think  this 
will  help  very  materially  in  getting  quiok  action  as  I 
put  Mr.  Edison's  letters  first  before  any  others  and  keep 
the  file  in  a  drawer  in  my  desk. 


As  you  probably  know  I  am  the  officer  on  special 
duty  in  Seoretary  Daniels  office  handling  all  the  business 
of  the  Naval  Consulting  Board  and  I  think  thiB  method  will 
be  the  best  one  to  follow.  With  the  immense  amount  of 
correspondence  coming  to  the  Navy  Department,  this  office 
alone  receives  three  thousand  letters  a  week,  it  is  not 
surprising  that  some  letters  go  astray,  so  if  this  idea 
appeals  to  you,  will  you  please  carry  it  out.  Address  under 
separate  envelop  carbons  of  letters  to  Captain  W.  S.  Smith 
Navy  Department,  Washington,  D.  C.,  and  let  the  official 
letter  come  as  you  have  heretofore  done.

Mr.  Edison  wants  to  get  small  samples  of  single  silk 
fibres  as  they  are  unwound  from  the  ooooon.  It  is 
for  very  important  Government  work  and  Lir.  Edison  would 
send  a  man  right  over  in  an  automobile  for  samples  if 
he  can  obtain  them.  He  also  wants  to  know  whether 
different  cocoons  give  single  fibres  of  different  thick¬ 
ness;  if  so  he  would  like  to  get  several  samples.

a  copy  of  the  dotijffsf^fa  which  I  am  sending  also  to  the 
Torpedo  Engineer  at  Newport  with  suggestions,  r---J  ~ 

Briefly,'  the  plan  is  to  spray 
flame  a  concentrated  solution  of  ammonium  r.iti 

simply  water,  as  at  present.  The  principle  characteristics  of 
NtUNOs  which  render  it  promising  are:: 

(1)  It  has  a  negative  heat  of  solution  and  a  positive 
heat  of  dissociation,  so  that  it  itself  furnishes  a  large  part 
of  the  heat  required  to  evaporate  it,-  dissociate  it  and  raise 
products  to  the  temperature  of  the  combustion  flask, 

(2)  It  is  very  soluble,  stable  in  solution  and  its 
products  of  dissociation  are  all  gaseous. 

(3)  It  may  be  used  in  the  present  type  of  torpedo,' 
no  change  in  construction  or  operation  except  that  the  water 
container  should  be  made  a  little  larger  in  proportion  to  the 
other  containers. - 

(4)  It  is  inexpensive  and  can

be  obtained  in  any  quantities. 


type  of  torpedo  engine,  there  apperas  to  be  a  gain  ( 
\5Yc  to  25*  in  power  to  be  expected,!  depending  on  thi 
of  the  solution  used.-  This,'  in  turn  depends  on  he 
temperature  at  which  he  torpedo  is  likely  to  be  usi 

t4fc  VTXAA.0X U»VV  A-O-tu&jtity  uA%A.  XlrnKfii*t>XZ\Aj\ 

In  making  this  calculation  we  have  not  taken  i 
the  possibility  that  some  of  the  N20  which  is  forme! 
decomposition  of  NH+NOs  may  further  dissociate  into 
and  oxygen.;  If  this  happens  to  any  great  extent  it 
considerable  additional  advantage  for  two  reasons:'  I 
dissociating,.  N20  liberates  a  large  amount  of  heat; 
oxygen  from  dissociation  would  aid  in  supporting  con 
thus  enabling  the  dimensions  of  the  compressed  air  1 
diminished.-  ?,'e  have  not  included  this  effect  in  out 
because  of  the  uncertainty  regarding  the  distribute 
temperature  in  the  combustion  flask,!  whose  average  t 
supposed  to  be  about  705°C.-  (N20  is  said  to  dissoci 
300°.  and  I775°.C,.  but  its  tendency  to  dissociate  depe 
on  the  pressure  and  the  nature  of  the  gases  with  whi 
mixed.-  ?/e  have  indicated  to  the  Torpedo  Engineer  ho 
amount  of  the  dissociation  may  be  determined  and  all 

Of  all  the  things  yet  tried,'  the  use  of  oxyger 
to  offer  the  greatest  promise,  if  the  heat  can  be  c<: 
At  the  torpedo  Station  they  described  to  me  the  troi 
they  had  in  attempting  to  use  oxygen.-  The  most  seri 
tendency  of  the  combustion  flask  to  melt,'  or  of  the 
the  flask  to  the  turbine  to  melt.'  They  were  unable 
this  by  spraying  in  water,'  because  the  water  formed 
in  the  spraying  tubes  or  behaved  like  water  on  a  re: 
and  allowed  the  metal  to  melt  under  it.- 


It  occurs  to  me  that  it  might  be  possible  to  1 
flame  temperature  to  the  point  where  it  could  be  hat 
using  a  solution  of  water  in  the  alcohol  fuel.  i.v  i

now  used.-)  This  would  amount  to  introducing  a  small  amount  of 
water  right  into  the  flame  in  such  a  way  that  it  would  have  to 
evaporate,-  and  I  should  think  that  the  flame  temperature  might 
be  reduced  sufficiently  to  enable  the  rest  of  the  heat  to  be 
handled  in  the  same  manner  as  at  present.' 

There  is  the  possible  objection  that  the  inflammibility 
of  the  alcohol  might  be  reduced,  by  the  solution  of  this  water,- 
so  that  the  flame  might  go  out  or  the  combustion  might  be  incom¬ 
plete.'  Does  any  reason  occur  to  you  which  would  lead  you  to 
feel  that  experiments  along  this  line  would  not  be  worth  while? 

I  have  written  about  this  to  the  Torpedo  Engineer  also,-  and 
am  thinking  of  making  some  tests  as  soon  as  I  can  get  to  it. 

While  in  Newport  I  went  through  all  their  correspondence  relative 
to  the  use  of  compressed  oxygen,  and  I.  do  not  believe  that  this 
method  of  partially  controlling  the  temperature  was  suggested.- 

Respectfully  yours.

Dear  Sir:- 


Personal  &  Important , 


Knowing  of  your  remarkable  work  in  favor  of  our 
Country,  and  seeing  lately  some  reference  to  your  ideas  as  to  the  most 
efficient  ways  to  overcome  the  Kerman  Submarine  Peril,  -  it  has  occur¬ 
red  to  me  that,  aB,  by  the  UBe  of  an  immensely  powerful  magnet,  it 
would  perhaps  be  possible  to  attract  steel  torpedoes  to  a  steel  vessel, 
so  there  might  be  some  force  in  nature  that  might  be  used  to  repel  them, 
or  at  least,  cause  them  to  so  lose  their  orientation  as  to  become  harm¬ 
less:  in  other  words,  using  first  the  idea  of  the  magnet:  as  vessels 
are  equipped  with  guns,  they  could  also  be  equipped  with  these  powerful 
magnets,  which  could  be  trailed  in  the  water,  in  the  danger  zone,  a 
sufficient  distance  from  the  vessel  to  attract  the  torpedo  to  the  mag¬ 
net,  thus  rendering  the  torpedo  harmless. 

If  this  is  not  practicable,  or  in  case  it  is  deemed  better 
not  to  use  it,  and  the  idea  of  the  repellent  force  can  be  made  avail¬ 
able,  then  this  repellent  force  can  be  availed  of,  to  either  stop  the 
torpedo  before  it  reaches  the  vessel,  or  deviate  it,  and  in  either  of 
these  effects  being  brought  about,  thus  rendering  the  torpedo  harmless. 

All  this  may  be  impracticable,  and  I  trust  in  this  event,  you 
will  pardon  me  for  occupying  your  valuable  time,  in  view  of  the  motive 
that,  as  an  American,  inspires  thiB  letter. 

With  the  highest  respect, 


Believe  me,

Mr.  Wolf  came  over  yesterday  morning, 
bringing  in  a  searchlight  shutter  and  lamp, 
and  this  equipment  was  immediately  turned  over 
to  lieutenant" Libbey,  who  conducted  tests  on  it 
in  the  laboratory  in  the  morning,  and  in  the 
\  afternoon  tests  out  of  doors  were  held. 

^  I  wish  to  express  my  thanks  for  your  in¬ 

terest  and  work  on  this,  as  it  seems  to  be  a 
.'great  step  in  the  right  direction,  and  inasmuch 
/as  we  cannot  accept  any  equipment  gratuitously 
'  we  will  have  to  say  that  we  will  accept  this  for 
"test". 

As  Mr.  Wolf  has  probably  told  you,  we 
have  been  working  on  more  or  less  the  same  lines 
ourselves,  the  only  difference  being  our  shut¬ 
ters  are  heavier  and  not  electrically-operated. 


We  are  taking  this  present  shutter  of 
yours  and  adapting  it  to  fit  one  of  our  lights 
and  probably  will  issue  it  to  one.  of  the  ships 
of  the  fleet  for  experimental  use  to  determine 
any  modifications  that  may  be  found  necessary. 

We  are  also  trying,  as  Mr.  Wolf  probably 
mentioned,  a  light  shutter  on  the  outside  of  the 
lamp  itself,  which  promises  to  be  satisfactory. 

I  am  afraid  that  very  rapid  signalling  by  this 
method  will  never  attain  as  high  speed  as  by 
sound  on  account  of  the  tendency  of  the  eye  to 
rush  flashes  together  at  high  speed.  I  think 
v/ith  your  shutter  we  will  probably  have  reached 
the  limit  of  speed  possible,  unless  we  can  make 
some  sort  of  shutter  that  will  act  more  or  lesB 


like  a  quick  return  motion,  that  is,  give  us 

success. 

With  best  of  wishes , 

Sincerely  yours.

contact  segments  can  bo  observed .  A  rotatable  drum  of  in¬ 
sulating  matorial  ia' mounted  on  a  fixed  stud  attaci.od  to  tho 
caao.  x.hio  drum  ia  driven  by  tho  phonograph  motor  and  mnhee 
ono  revolution  per  minuto.  It  carries  two  colloctor  rings 
through,  which  cloctrical  connection  ia  obtained  to .operate 
tho  epoed  controlling  relays: .  Wo  have  shown  the  aocond 
hand  lengthened  approximately  .G  of  an  inch  on  tho  back  of  - 
tho  movonont  and  projecting  through  tho  fixed  stud.  Its  outer 
ond  carries  a  pointer  about  tho  sawo  longth  as  tho  aocond  hand 
and  affixed  thoioto  in  tho  same  way  as  the  second  hand  is 
attached  to  the  othor  ond  of  the  shaft.  Shis  pointer  carries 
a  platinum-iridium  ball  contact  at  itc  ond . and  makes  contact 
with  either  of  tho  platinum  contact  sognonta  mounted  on  the 
insulating  dial  whenoverthe  latter  tends  to  go  faster  or 
slower  than  the  clock.  2ho so  contacte  scud  .out  corroctivc 
impulses  to  the  spoed  controlling  roluys  and  through  suitable 
governing  moans  bring  the  motor  back  in  stop  with  the  clock.  • 
The  curront  from  tho  relays  is  completed  through  tho  clock 
frame  and  soconrt  hand  shaft  to  tho  pointer.  We  aro  unsblo 
to  stnlo  'just  how  much  pressure  will  bo  required  between  tho  , 
pointer  contact  end  contact  segments,  but  it  ooeqs-that  a  very 
light  contact  •.-.which  will  not  interfere  witii  the  clock  operation 
will  bo  sufficient;.  ,  Wo  expect  to  nso  a  current  of  .01  ampere 
at  12  volts.  You  will  noj;o  that  wo  have  made  provision  for 
tho  contact  arm  to  wipe  ovor  the  segments.  this  is  for  con¬ 
venience  in  starting  -  the'  motor  only  as  it  .allows  tho  motor  gov¬ 
ernor  to  bo  adjusted  until*,  it.  is  "running  in  approximate  syn¬ 
chronism  with  the  clock. 


-2,- 


la  tho  running  position-  tho  pointer  will  bo  between  the  con¬ 
tact  segments  and  the  eorroctivo  impulses  will  act  on  tlio  governor 
beforo  any  wiping  tskos  placo.  Vie  huvo  shown  no  moans  for  . 
holding  tho  movement  in  tho  case,  but  tho  latter  can  probably 
bo  modified  to  suit  the  movement  when  designing  tho  dotuils. 

It  will  also  bo  nccesoar.  to  make  tho  distance  from  tho  attach¬ 
ing  base  to  tho  movement  long  enough  to  pcarrait  tho  oasy  insertion 
and  operation  of  the  winding  key,  but  as  no  I:ey  was  sent  with  the 
movement,  wo  wore  unable  to  dotermino  this  dimension.  Tho 
proximity  of  the  vertical  driving  shaft  to  tho  koyholo  may  also 
noooesitato  a  special  key. 

Wo  are  submitting  this  scheme  for  your  comnonts  and 
would  bo  glad  to  recoivo  apy  suggestions  that  you  may  bo  able 
to  make.  If  tho  schomo  appears  feasible,  as  shown,  we  would 
like  to  have  you  alter  two  movements  by  longthoning  tho  shaft 
us  shown  and  send  thorn  to  us  ns  soon  as  possible.  This  should 
include  dial  glasses,  bezels  and  keys  and  if  you  could  send  us 
a  standard  caso^it  might  be'  of  somo  assistance  to  us  in  design- 
ing  tho  novouont  holding  nocne  in  the  special  case.  Two  of  uhc 
small  bushings  which  are  attachod  to  the  second  hand  could  also 
bo  used  to  advantage  in  securing  tho  contact  pointer  to  tac  shaft. 
Wo  will  make  up  all  parts  except  those  abovo  requested.  If  it 
is  not  feasible  to  lengthen  tho  second  hand  shaft  as  much  as 
roouootod,  it  would  probably  be  satisfactory  to  lengthen  it  enough 
to ‘apply  a  coupling  by  which  a  pointer  shaft  could  bo. .driven. 

Wo  assume  that  it  will  bo  satisfactory  to  return  tho 
movement  which  you  sent  us  when  tho  altered  movements  heroin 
ordered  havo  been  rocoivod  as  we  may  need  to  rofor  to  it  during 
tho  nrogroos  of  this  work. 

bo  would  bo  glad  to  hoar  from  you  as  soon  as  possible, 
and  thunk  you  for  tho  prompt  attention  given  to  our  original 
rotiuost. 

Yours  very  truly.

Gentlemen:- 

V/e  have  your  letter  of  June  Oth,  and  will  proceed 
to  fit  up  two  of  our  6-Day  movements  for  your  apparatus.  V'e  pro¬ 
pose  to  mount  a  hollow  stud  on  the  movement  plate  to  carry  the 
bearing  next  to  your  pointer  socket.  This  will  protect  the  long 
and  slender  pinion  shaft  and  be  very  much  safer  to  handle.  We 
will  make  the  length  of  this  stud  1/A  size  or  your  drawing,  and 
propose  to  make  the  outside  diameter  of  the  stud  0.16  inch. 

We  are  sending  you,  under  separate  cover,  one 
Model  X  Case.  This  is  designed  for  automobile  use  and  may  not 
be  suitable  for  your  apparatus,  but  you  may  be  able  to  substitute 
a  flat  cover  with  a  container  for  your  contact  device  in  place 
of  the  screw  back  on  this  case.  Our  movements  would  be  fitted 
with  dials  and  hands  of  proper  dimensions  for  this  case.

for  tho  production  of  high  oxplosivos  and  of  ammunition. 

Ono  of  tho  most  ossential  requirements  in  tho  co¬ 
ordination  of  tho  industrial  resources  of  tho  country  for  tho 
successful  conduct  of  the  war  is  to  provide  a  regular  and  ade¬ 
quate  supply  of  fuel  to  tho  important  utilities  engaged  in 
enterprises  through  which  they  rendor  service  to  the  Govern¬ 
ment  and  to  the  public.  To  facilitate  solving  tho  many  prob¬ 
lems  affecting  tho  continuous  supply  of  fuol  to  operate  their 
plants,  tho  National  Coal  Board  ha9  boon  ploasod  to  appoint 
hr.  Goorgo  W.  Elliott,  Socrotary  of  tho  Committee,  to  member¬ 
ship  on  tho  Coal  Committoo.  A  questionnaire  is  now  being  pre¬ 
pared  which  will,  within  tho  next  fow  days,  be  forwarded  to 
ovory  gas  and  olootrio  light  and  power  company  .in  tho  country, 
asking  thorn  to  sond  a  statomont  of  tho  various  kinds  and 
quantitios  of  fuol  oach  usos  por  annum  for  its  various  pur¬ 
poses,  tho  wator  or  rail  connections  over  which  thoy  are  re¬ 
ceived,  together  with  a  monthly  statoment  of  fuol  contracted 
for,  received  and  consumed.  This  will  onablo  tho  Committoo  to 
givo  prompt  information  to  tho  authorities  of  fuel  shortage  in

any  particular  locality,  with  the  transportation  linos  in¬ 
volved,  loading  and  unloading  dela.ys,  car  shortages,  routing 
and  trans-shipmont  difficulties,  otc. 

The  Coramittoe  has  been  in  consultation  with  the  au¬ 
thorities  on  mattors  affecting  tho  service  which  the  employees 
of  tho  Companies  may  render  to  tho  Government  and  in  rogard  to 
various  questions  connoctod  with  selective  registration,  con¬ 
scription  exemptions  and  provision  for  the  dependents  of  em¬ 
ployees  who  may  be  called  upon  to  rondor  military  service. 

Tho  furnishing  of ’.heat,  light  and  power  service  to  the  troop 
cantonments  for  tho  mobilization  of  tho  military  forces  loca¬ 
ted  in  difforont  parts  of  tho  country  is  now  being  considered 
and  information  is  being  collected  as  to  how  these  agencies 
may  be  made  available  to  the  camps  in  the  shortest  possible 
time  from  the  nearest  points  of  supply.' 

It  is  believed  that  this  National  Committee  on  Gas 
and  Electric  Service  can  be  of  great  assistance  to  the  Govern¬ 
ment  in  these  several  directions  and  that  it  will  oover  a 
broad  field  of  useful  and  patriotic  servioe,  bringing  to  bear 
on  the  successful  conduct  of  the  war,  from  the  standpoint  of 
efficient  industrial  mobilization,  the  vast  resources  of-men 
and  facilities  which  the  utility  companies  of  the  country  have 
at  their  command  and  through  which  they  are  now  efficiently 
serving  the  public  and  which  they  desire  to  make  available  to 
the  Nation  to  the  greatest  practicable  extent.

MR.  THOMAS  A.  EDISON, 

Thomas  A. Edison,  incorporated. 

West  Orange,  New  Jersey, 
liy  dear  Mr  .  Edison; 

This  is  to  confirm  my  telephone  conversation  with 
Mr.  Meadoworoft  relative  to  special  vacuum  tube  amplifiers 
constructed  in  a  manner  to  reduce  to  a  minimum  the  effect  of 
any  possible  mechanical  vibration. 

As  I  explained  to  nr.  Meadoworoft,  we  will  have  to 
make  up  these  tubeB  specially  and  I  am  not  at  all  sure  how 
successfully  they  will  accomplish  the  results  which  you  deBire. 
The  tubes  which  you  are  working  with  have  such  enormous  ampli¬ 
fying  power b  that  the  problem  of  so  arranging  the  internal 
structure  as  to  completely  eliminate  all  chance  of  difficulty 
due  to  mechanical  vibration  is  more  serious  than  it  would  be 
if  the  tubes  were  less  efficient.  As  soon  as  we  have  any 
models  of  the  new  tubes  ready  I  will  see  that  they  are  sent 
out  to  you  for  trial.  As  I  told  Mr.  Meadoworoft,  it  will 
probably  take  us  three  or  four  days  to  accomplish  this  work. 

yours  very  truly,

and  tho  sample  son!  us  has  boon  of  considerable 
assistance  to  us  in  designing.. 

y/c  agroc  with  you  that  mounting  tho  hollow-

ance  with  the  construction  and  dimension;  outlined

by  sliming  on  a  bushing  of  tho  right  length  to  prop-

providing  this  flange  is  located  in  accordance  with

you  will  thread  the  outer  ond  of  tho  stud  -for  a  short

Thomas  A. Edison, Esq., 
President, 

Naval  Consulting  Board, 
Orange, N.J. 


Dear  Mr.Edison:- 


Enclosed  herewith  please  find  a  copy  of  a  letter 
from  General  Goethals,  attached  to  which  is  a  report  of  a  special 
committee  appointed  some  time  ago  to  study  the  question  of  pro¬ 
tection  of  merchant  vessels  from  being  sunk  by  submarine  attack. 

The  Naval  Consulting  Board  has  been  studying  and 
experimenting  upon  the  submarine  problem  from  many  angles.  The 
question  of  proteoting  the  ship  itself  is  a  problem  distinct  from 
all  others  and  the  one  of  greatest  importanoe. 

In  order  to  get  concentrated  work  and  quick 
action  I  have  been  oooperating  with  General  Goethals,  through 
a  small,  special  committee,  in  which  the  Naval  Consulting  Board 
is  represented  by  Mr. Hunt,-  the  other  members  of  the  committee 
being  Admiral  Rousseau  and  William  T. Donnelly,  engineer  and 
marine  architect,  an  expert  on  flotation. 

This  oommittee  has  eliminated,  after  a  study, 
the  various  devices  known  as  nets,  pontoons,  blisters, eto., 
beoause  of  the  interference  in  the  speed  of  the  ship,  which  is 
of  the  greatest  importanoe,  and  beoause  of  dangers  involved  in 
rouoh  seas  and  interference  with  docking.  A  further,  and  very 
important  consideration,  is  that  the  mobility  of  the  ship'..should  not 
be  disturbed. 


You  will  note  that  there  are  six  items  in  this 
report,  making  speoifio  reoommendations.  All  but  Item  No. 6  are 
of  a  seoondary  importanoe,  being  in  the  nature  of  proteotive  safe¬ 
guards.  Item  No. 6  offers  a  praotioal  solution  of  the  question 
of  keeping  a  ship  afloat  after  being  torpedoed. 

A  ship  loaded  with  lumber  oannot  be  sunk  through 
torpedo  action.  It  will  become  water-logged. 

The  proposition  is  to  fill  up  the  unused  air 
spaoes  below  the  deoks  and  within  the  hold  of  a  ship  by  small 
wooden  water-tight  containers  and  to  so  load  a  ship  that  there 


Thos.A.Edison,Esq.,-2. 


will  not  be  space  enough  for  water  to  replace  lighter  material 
even  though  the  ship  be  water-logged. 

This  renort  is  in  the  hands  of  the  merchant  shipping 
people  in  New  York  and  we  are  now  figuring  on  the  oost  of  an 
equipment  for  a  ship  of  about  10,000  tons  capacity, 

X  have  personally  presented  this  report  to  President 
Wilson  and  to  several  members  of  the  Cabinet,  it  being_ our 
intention  to  reduce  insurance  rates  in  proportion  as  tnese 
protective  devices  are  applied. 

Yours  truly,

will  drop  other  work  to  do  this  for  him  and  give  him  quiok  serv¬ 
ice.  In  suoh  matters,  perhaps  you  had  better  write  to  me  person¬ 
ally,  so  that  I  oan  push  it  through  our  works. 

In  the  spirit  of  helpfulness,  believe  me  to  be,

Mr.  Thomas  A.  Edison, 

Llewellyn  Park,  N.  J. 

Dear  Mr.  Edison: 

The  war  has  plunged  me  into  so  many  business  prob¬ 
lems  that  X  fear  X  will  find  little  time  for  public  work. 

I  son  devoting  myself  primarily  to  the  relieving  of 
the  fuel  supply  by  increasing  our  oil  and  natural  gas  production 
and  finding  means  of  getting  it  to  the  market.  Between  jobs,  and 
while  on  the  trains,  I  find  some  time  to  think  of  the  big  problems, 
but  often  do  not  know  how  to  set  these  thoughts  in  motion. 

As  you  can  imagine,  my  contributions  would  be  rather 
scattered  in  character,  as  my  life’s  work  has  been  devoted  to  so 
many  different  lines.  I  therefore  will  probably  have  to  put  my 
thoughts  in  motion  largely  through  other  people. 

You  are  the  last  man  I  would  have  expected  to 
bother,  because  I  feel  that  every  second  of  your  time  is  valuable, 
and,  in  common  with  many  other  people,  I  am  hoping  that  you  will 
accomplish  wonderful  things—  and  if  I  were  a  praying  man  I  would 
be  praying  for  more  power  to  you. 

It  seems  to  me  that  our  effectiveness  in  this  war 
must  depend  almost  entirely  on  new  methods.  We  cannot  hope  in  a 
few  months  to  train  our  men  to  a  military  efficiency  equal  to  those 
who  have  been  trained  for  a  lifetime —  and  it  did  not  occur  to  me 
until  the  other  day  that  possibly  new  methods,  unless  kept  secret, 
might  prove  of  more  value  to  our  enemies  than  to  ourselves,  which 
I  will  attempt  to  illustrate  by  an  example  I  will  give  you  later.

I  have  heen  convinced  for  some  time  that  the  best  oppor¬ 
tunity  for  ub  to  effectively  contribute  our  share  in  this  war  was 
by  teaching  ourselves  and  our  allies  the  value  of  what  I  might 
term  to  be  "dollar  efficiency". 

The  weakness  of  nearly  all  of  the  European  work  is  the 
utter  disregard  of  "dollar  efficiency",  or  Thompson's  Rule.  If  an 
Englishman  builds  anything  he  wants  to  make  it  last  forever,  when 
by  the  use  of  cheaper  materials  the  saving  on  first  cost  would 
build  a  new  structure  every  few  years.  The  German  sneers  at  the 
low  wheat  production  in  our  American  fields,  and  yet  an  attempt  to 
bring  our  production  to  the  Bame  yield  of  wheat  per  acre  would  mean 
higher  priced  wheat. 

American  business  men  seem  to  know  instinctively  the 
value  of  "dollar  efficiency".  All  government  work,  both  here  and 
abroad,  seems  to  disregard  this.  Government  engineers  insist  on 
a  thoroughness  and  refinements  which  brings  an  unnecessary  cost. 

I  know  to  talk  about  "dollar  efficiency"  would  be  offen¬ 
sive  to  a  great  many  people.  The  foreign  governments  have  already 
learned  this  lesson  somewhat,  when  it  has  been  forcibly  brought 
home  to  them  that  unnecessary  refinements  curtail  the  total  pro¬ 
ductiveness  of  a  group  of  men. 

In  trying  to  give  you  an  example  of  what  I  term  "dollar 
efficiency"  and  also  the  danger  of  Yankee  ingenuity  proving  more 
valuable  to  the  Germans  than  to  ourselves,  I  will  have  to  give  you 
as  an  illustration  one  of  my  latest  ideas,  and  one  that  is  not  yet 
even  in  a  "half  baked"  state;  but  I  do  this  because  I  do  not  think 
any  time  should  be  lost  in  pointing  out  the  danger  we  are  in  if  we 
should  show  Germany  how  to  solve  some  problem  which  otherwise  may
